Sorry if this ends up being a double post, my internet blipped and I lost the post I wrote
I can add my personal experience to glasscages.com, very disapointing. The tanks I got from them were amphibian/reptile tanks - not fish - but if that was how they build their tanks then I fear for the fish tanks. In addition to price and workmanship, I also have to add that there is an obvious lack of engineering with their designs. I get my custom tanks from a friend in LA who really knows what he's doing (gorgeous tanks), but likely someone on here knows a more local aquatic tank builder.
I'm not a fan of acrylic (they scratch so easily for me) and while I'll admit that there are certain applications that acrylic would likely be better than glass, at that size I think glass would be the way to go, and cheaper. A big benefit with acrylic is that it's lighter, but even with acrylic your tank will be heavy enough just with the water that you'll still need to do some serious work to make sure the hutch table can support it!
