Need advice on buying new aquarium

[bradleyheathhays]

I'm looking for a new regular sized 125 gal aquarium (72" x 18" x 24" tall) and since all aquariums look about the same to me I thought I'd write in to ask what I should be looking for design feature wise in this new aquarium. Which brands should I look for and which ones should I specifically avoid? What design features should I look for? I want a well built aquarium, but at the same time I'd like to do it as cheaply as possible.

Thanks
