I am in the same shoes you are budster and I also agree you get what you pay for. I bought 2 aeration systems(eBay) and a windmill for my pond because I could not afford the Cadillac vertex systems. Well I wasted 2-3 years aerating my pond with systems that gave me nothing but trouble. I have 2 compressors collecting dust and a windmill that's bent to crap because a 100mph wind and 1000ft of poly pipe that I can't wait to cut into pieces and make structure( hope I can sink it! Never had much luck at sinking that mess when it was an aeration setup). I spent $4000 on crap that doesn't work now.
The happy ending is my Cadillac vertex system I bought is flawless in every way.
I want a feeder also but I am waiting until I can buy the texas hunter. If I buy something different it will put me that much further from it.
Hope this helps and I hope you stick around like the rest say Greg is a great guy and he knows how to get a good bang for your buck and get fast results.
