I considered them then decided to go store bought to be cheap. I corresponded with them, and yeah they were a bit terse but answered all my questions to my satisfaction.
Just an FYI. A guy in the local fish club bought a 300 from them that the back panel cracked after about a year. The tank was on his hom made stand. I couldn't believe it, but they replaced it! All he had to pay was a $50 freight charge on their truck.
