I know of a couple of pro installers that have (or at least had) the DPS12, and it knocked a picture off the wall during King Kong. POs the neighbors plenty.
For the money, and perhaps also because of tougher pricing/shipping in CA, I'd look to build one. Check out the Kappa Perfect in the DIY subforum, or if you don't mind a VERY large sub, or causing structural damage to your home, check out the Tuba. They should both fall considerably under budget, but break the budget maybe slightly when you add the amp.
I've never built a sub, but if I did it all over again, I probably would with help from a friend.
edit: Oh, if DIY is impossible for you, SVS has a dealer in CA, you'll have to wait for someone to chime in on that, or just use the search functions in this subforum.
