First I should qualify that I am a dealer for Vmps but that's all I'm a dealer for. If you want a great sub for the money you should get one of the Vmps subs. They're fast, articulate and powerful as you could want. For the money they're of the best you can get.
Another companies subs I really like is the M&K's. It seems they don't bring much respect from most in the sub department but I can assure they're quite good. A used one in your price range will do very well. I suggest these because used prices are unrealistically low imo. I do know that Martin DeWulf of Bound For Sound uses an M&K sub with his Vmps RM 40's.
If you order the Vmps sub as kit you could get the Larger sub with a built in amp. With two 15" drivers and a 12" you'll have all the first octave bass you want. Low distortion and fast enough to keep up with planar speakers.
I've not heard the Rel subs but alot of people think alot of them. They would be worth a try too. I'd stay away from SVS and the other boomer type subs that are better for movies than music.
