idk if im allowed to put up another site on here, but maybe you should consider building the tank yourself (with a friend to help...)
they have plans on garf.org (i think its .org) ... i think it might be under DIY
anyways, its pretty much plywood and then one peice of glass or some other clear material. you could get everything to make it at home depote... its legit, ive seen alot of these sort of tanks and they seem solid.
(if i cant post garf then - admin can just delete? dont be hatin
)
