which one are you looking at. I just last night converted my 55g to a sump so I'm in no need of my wd-200cs. i believe its that one. I thought compared to the megaflows and such that this was just as good, but the kicker a lot cheaper. i will be putting mine up here on the classifieds so let me know if your looking at something like this.
even if you don't go with mine definately a vote for it being a good choice.
