Thought I'd chime in
My tank is 60" x 30", not exactly what you're looking for. I can say that I'm very happy with Planet Aquariums.
Don't let the naysayer's talk you out of what you want. Bigger is NOT better. As long as the tank is big enough to hold what you want to put in it, well, size is up to you. It's your tank, right? Do what makes you happy.
Had a bunch of folks knock my wide, shallow idea. You know what? I'm VERY happy with it. Don't get my shirt sleeve wet when I'm messing in the tank, and it fits perfectly in the niche I wanted to fill.
