Ben,
Sorry I didn't get back to you tonight... Friday will work better.
If you don't get any responses, check out glasscages.com. I just picked up a 50 tall (36x18x17) for $70. Stands and canopies leave a little to be desired, but the tank quality is pretty good. Still some sloppy silicone, but you can clean that up if needed. I'm using mine as a sump, so appearances are not a problem. He is using plastic frames now on the tanks, which looks better than some of the older styles I've seen. Can't beat the price.
