I bought this one locally. It's made by Aqua Pro and my LFS stocks them. The guy there told me that Aqua Pro only sends out these and a couple other dimensions of rimless tanks to distributors, and the ones they have listed online are a small part of the full lineup of sizes they offer. I believe the guy that started Aqua Pro had a store here in Seattle for a while (or so i heard) so the stuff is available in a few stores locally.
The glass is 3/8" or 10mm and the seam quality is very good, normal iron glass. Cost me $110+tax for the tank.
I have another 12"x12"x12" cube from the same store made by AquaPro that uses 1/4 or 6mm glass which i'm also very happy with. same great seem quality and it's starfire as well. That one sas $60+tax
Right now I have quite a collection of 30 in lighting so this is great to know. Thank you for the insight.
