Speakerbuilder.net, great site!
Forgot to add, I'm building the DHT CC (dual woofer horizontal version, not posted yet, but I have the crossover+layout plans) for my own HT, all I need to do is build the XO, and finish the cabinet. From my experience with the Dayton 5.25inch woofer, it's a STEAL @ $13.50.
I can't wait to finish it. Should have no trouble smoking a $150 Paradigm CC150 or a PSB 8C.

Paldo, do you know anything about building a subwoofer? I have seen www.partsexpress.com where you can supposedly build an awesome subwoofer for under $200. I have seen a nice subwoofer and amp, but know nothing about other needed parts. >>
Check my sub using Parts Express parts in my sig.
15inch Dayton DVC - $132
275watt RMS @ 4ohm plate amplifier - $135
Total cost was about $300 (still haven't put on the mahagony veneer, so it's not much of a looker...yet).
Best part? Raping Velodyne, Cerwin Vega, Def Tech subs that cost 3x as much.
115db @ 20hz, in a ~2500cf (~320sq. ft) room is sweet
What would my recommendation be for $200?
Get a good driver, like the 15inch DVC, and make an infinite baffle sub.
This is one like you'd have in an attic; one side plays into the listening area, and the other vents into the attic (or basement, same difference). The benefit of this setup is you get a TON of subsonic bass, your whole house shakes instead of just the HT room, you dont need as much amp power, EXCELLENT transient response (IE: very tight, clean, no-overhang bass), and of course, no box so the GF/Wife doesn't complain
$80 for the 120watt plate amp
$132 for for the 15inch Dayton DVC (600watts RMS, 32mm linear stroke, 5 year warranty)
I have quite a few other recommendations(driver and amps and box sizes), just LMK whether your willing to go with the Infinite Baffle sub or you really want a boxed sub.
