Where is the cheap one!! They want $65 bucks for the one in the link! By the time you get the hoses and quick-connects you are over $100 bucks for a hydro setup. In the same catalog you can buy 12V electric geared motors for under $20 and all you need is wire and a switch. I did my conversion for less than $20 using a power window motor and switch from a junk yard. this thread will tell you all about it. Click here
