Not quite what you asked, but I was looking to move up to a 75 bowfront and ended up with a 65 Flat Back Hexagon. My LFS had a custom made one that never got picked up, so it was a bargain- $950 for the acrylic tank with overflow, and a solid mahogany stand and canopy.
I really like the look of the Flat Back Hex. I know Tenecor makes a 135 acrylic for about $1,000 with a dual overflow kit (stand/hood runs about the same).
So many possibilities....I happened to fall in love with this one just wandering around different stores.
