Yeah.. i agree with rookie on the 55G tanks. Some people like that slim footprint that the 55G tank provides, but i've heard more people complaining about it then not. Including myself. I hated my 55G tank because it was so tall, and so thin. It gave me almost no room to do the type of aquascaping that i really wanted to do. If anything, look for a 50G tank.. or a 50G/40G Breeder style tank. Those tanks have the best footprints IMO. They're 3ft in length, generally shallow, and are wide.
Try glasscages.com They make some pretty good tanks from what i hear, and they have a couple drop-off points to where they will either ship the tanks for a fee, or they will bring the ordered tanks with them to conventions that they go to, which happens to be all over the country. They were just in my state a few days ago, i think last sunday. But they are mainly stationed in Tenessee so.. Yeah. I would say CL or an order from an LFS like mgamer said, would be your best bet to finding the tank that is right for you.
