Just talked with glasscages. They will do euro-bracing. They usually also include a plastic trim around the top and the bottom of the tank as well. I asked about being able to leave them off and he said he would leave the top off if I wanted but not the bottom (but that I could remove it if I wish). Not sure why they can't just leave the bottom trim off, but not a big deal for me (he mentioned it was only for appearances). The low-iron glass they use is Ultra-White, not Starphire.
All-in-all for my funky sized tank (52x22x24), with front AND back low-iron glass, and 8 bulkhead holes (no overflows - I'm building those myself) the quote I got was really good (from what I was expecting).
The deadline for getting something built for the Dallas delivery is like right now. Probably got another day to pull the trigger if anyone else is interested. I'm gonna think about it overnight and hope Keith gets back to me with a quote by then from Universal before I decide...
