Here is my recent review of Envision Acrylics:

It's definitely worth it to at least give James at Envision a call. He is a really nice guy and easy to talk to. Yes, it will probably be more expensive for the tank, but imo, it's worth it. I called TruVu when I was shopping too. There is probably a big difference in thickness of acrylic used. My 105g corner pentagon is 1/2" acrylic, TruVu's version was 3/8".
