I have a couple sumps in the garage. One is a DIY sump and wet dry tower that was in the stand under my 58 (it has a space for a fuge built in, or it can be run as a seperate tank). The other is a store bought wet dry, that came with an overflow. The only drawback to it is its got a pretty good size crack in one end. Its been repaired but its a little unsightly. I will try and find/get some pictures (I can't find the cord to DL pictures from my camera to my PC right now). I think $20 for either of the sumps is fair and $15 for the overflow.
