Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!
