Not much depending on what your looking for. If you are open to an used fork maybe on such places like E-Bay or Craigslist or even the classifieds here on the forum. If you need 120mm travel; IS disc specific; 20mm axle; lockout; preload; and compression I think new buy you may have to get around $425 or so. But you never know from all the online retailers who may be having a great sell going on or trying to unload new old stock. You just have to go and look for these things and do searches to find it.

If you are open to a used fork you may find a great deal. This one on E-Bay may fit your need and is new uncut steerer tube as well but is a air fork but has 20mm axle and is black with disc brake specific: http://cgi.ebay.com/ws/eBayISAPI.dll...m=220554063255

Man you just have to look and see what you can find.
