Hey jsn, I have a 135 (72x18x24) from Glass Cages. Pretty much everything I've read about them online has proven true in actual experience. It's pretty heavy duty. With the extra glass reinforcing the seams on the bottom, I can't see this thing ever leaking.
Pros:
*Great price
*sturdy build
*If I'm not mistaken they will do some custom work at your direction for relatively cheap
Cons:
*Silicone job isn't the greatest...but the excess cleans up quickly and easily
*Shipping cost may negate any savings, but if you can pick up at a show I think it's not too bad
* standard plastic bracing on the tank isn't great but you could always get them to give you some sweet bracing like Louey's tank (yum!)
* on my tank, the cross braces are at 18" centers not 24" like on other manufacturers' tanks. I don't think this will be a problem for the dimensions you are looking for, but anyone else looking these tanks needs to consider this as far as lighting is concerned. I was thinking about 3-400w. SE's for the standard 135, but it looks like with the 18" spacing I need 4-250w. DE's, or 2-400w center and 2-250w on each end.
Overall, it's not fancy but the price is right and it's built well!
Best of luck!
