I have had a 270G and a 100G and currently have a custom 70G built by them and I was/am happy with the tanks.
If you are wondering whether they are a reputable builder, I would say that they are. They have been around for a long time and have built many tanks. I can't speak to their customer service because all of my tanks were bought 2nd hand. I hope it works out for the guy in the thread referenced above...it sounds like TruVu agreed to send him a new tank so that's a good sign. Things happen, but it's whether or not a company stands behind their product that matters.
I had heard that they relocated (they used to be based out of Northern CA), so hopefully they aren't having quality control issues as a result of the move.
