I will take some pics of my bench and post tomorrow. Also I used non weighted tubing and our local orange big box store has precut 18" pieces of 5/8 rebar. I bought several pieces of that and used zip ties to attach to the tubing in several places between my compressor and diffuser. I bought a vacuum pump off of ebay that was rebuilt, they usually have many on there for under 100 bucks. I got my tubing from that same orange big box store and im not sure of the price. My diffusers are 12" square stones that I ordered online for less than 25 bucks each. I have about $350 in my aeration system, not counting the wood to make the bench. My pond is .6 acres and 9' deep at the deepest part.
