As far as where you can get a cheap tank, look in the classifieds, or on ----. I just got my tank last week off of ---- for real cheap. It is a 75g - nice stand, with 85lbs lr, the water, filtration system, MH lighting canopy and light, some inverts, and lots of extras. I only paid $400. So there are good deals out there if you are willing to be patient.
