I would rather spend a little extra with Gene, or any of the other small "mom & pop" business's (Kent Wallace from livingwatersolutions comes to mind). Also, I think the more DIY projects we can build the better. I have a diy skippy on my small pond at work, and a larger diy sand and gravel filter/water fall on my larger pond at home, both work flawlessly, both were fun to build, and best yet, I learned something along the way. Two each his own though, just my 2 cents...
