Ou8me2 - Yeah, I usually go with the same thought process. The issue here is that I planned on building mine, which will take a bit. I can get the 10g sump, cheap skimmer, and socks all for $20 - Along with some macroalgae. It's a pretty good deal. We are getting carpet installed soon, and that's when I am going to drill my 40B and install the overflow system. I really just need something to "catch" the water and pump it back. That's the only reason I am thinking about going this route.
