I have the Velodyne CHT 12 for my home theatre system and just bought the CHT 8 for $149 online and after the initial break-in period it sounds pretty good. It's not the CHT 12 (or a Hsu), but it's a decent subwoofer from a high quality subwoofer manufacturer that is in your budget - even after shipping and handling - so if you don't want to save for something better it would be a good option.
