I have one and I like it beacause it is built well, skims well, and is inexpensive ($68 drfosters). It does not havea a collection cup so you hang a hose off of it into a milk jug or some other such container. When you turn it off to clean it you MUST unhook the hose, get the unit running, then hook the hose back on or a siphon may start. That is my only gripe about the unit, otherwise it works very well for what it is. Check out my gallery for some (tiny) pics.
