Take a look at the Pondmaster line of linear pumps. Rebuild kits are available for them. Just do a search, lots of places sell them.
I run 4 of them constantly and have had to put kits in two of the four after about approximately 10-12 months of continuous use. Rebuild kits run from $8 to $15 depending on where you get them and the shipping. I ordered 4 at $8 so the shipping would not be so much of the total. have used 2 kits so far. Takes about an hour for me on the first one and now about 15-30 minutes once I am more sure of the proper assembly. Not rocket science. Probably a competent person that did them regularly could do one in 10 minutes. Me - I'm old and slow - what can I say?
They make several different models depending on the air volume needs. I use the AP100's.
Only good to about 9-10' maximum depth because air flow is drastically reduced as depth increases (because of the design of linear diaphram pumps as opposed to a piston or vane positive displacement pump).
Probably other brands are better. The Pondmaster line is just cheap to buy and has rebuild kits available.

Are you looking for plug n play, or a DIY system?

Plug N play mainly but DIY could work if its not complicated...LOL assuming DIY will be less expensive?

Probably, but there's nothing quite like the ease of dropping a turn-key system in and firing it up. I think a lot depends upon the budget....have you checked out the pond lyfe systems from Vertex?

Bobby, I just received a brand new (out of box) 1/3 hp Gast 75R compressor/pump off Ebay for $80 shipped and they retail for over $500, along with a 30 day money back guarantee. The used ones were $250+ with no guarantee or return policy. I know this pump is major overkill for your 1/8a pond, but point being there's deals out there to be found, with a little patience (of which I have little ) I'm sure you can find one cheap. Then it's a matter of finding a diffuser. I also have 2, 100' unused rolls of 5/8" Bottomline weighted tubing. Let me know how much you need to run from the pond's edge to the diffuser and I'll ship it to you FOC.

I agree with Keith's Ebay comment. I've purchased several compressors, new and used, and have been well satisfied with all.

In some cases, yes. If you utilize the output it's a compressor, and if you use the input it becomes a vacuum pump.

Ask the seller what the outlet psi measures or the PSI rated for the compressor. It is also good to know the CFM rating (cubic feet per minute).

Yeah I also got a 1/3 hp gast off of ebay and am very happy with it. You may need to make the manifold for it and get a filter for the vacuum side and maybe a gauge but the pump is the hard part to find at a decent price.
I got all my extra stuff from Bill Cody, like my pressure gauge and my relief value, filters stuff like that. He was very helpful with all that.
Like said above 1/3 may be overkill, but 1/4 hp pump would be good like bill said check out the specs. Don't worry about your questions ask away I had the same questions when I first started doing this. Even about the vacuum pump... LOL. No question is a stupid question when your trying to do something for your pond!!

As rull of thumb what PSI and CFM should I want for aprox 10ft deep.
I understand the CFM drop drastically with every foot of water dept. I assume the the more the psi the compressor has the more CFM it will have at depth?

psi is 6, cfm depends on the diffusers and what they need to operate.

Yeah things can get a little complicated quick if you let them. If your going to do 2 diffusers at 10 feet a 1/4 hp gast should do that just fine easy in fact! My gast will run at 15 to 18 feet my normal water height is 9 feet and it boils like crazy at 9 feet. So if I have this right here is the deal.
You have to figure 1 psi for every 2 feet of water. So like Esshup said 6 psi would give your about 12 feet.
If the pump says it will do 3 CFM then you need to look at your fuser specks and see what it take to push the fusers per fuser. For example.
If I have to vertex fusers that will push at 1 cfm lets say I think it's less than that but lets keep it simple here.
I could then use 3 fusers in my setup cause my pump will push 3 cfm with 1 cfm going to each fuser. If you go with 2 fusers then you have 1.5 cfm going to each fuser which is ok too. Your fusers will have a min and max cfm rating. like .5 min, and 3 max per fuser. Your just have to make sure yoru in that range and your good. Which most times you are if your only using 2 fusers. Where this comes more into play is when your start adding 4 and 5 fusers to a group. Then it start to get tricky. Anyone please correct me if I am wrong here I am no expert on air but have learned a lot from here over the past 5 years.

Without looking up the specs, I think the Vertex diffusers are rated to "open" at .5 cfm and will take 4 or 5 cfm max. It's not good to run them at the minimum, all you need is a slight drop in cfm and the diffuser won't work.
