google. thats the best site for me to find and purchase what I want.

search based on your current fork's rake, axle to crown measurement, and style of brake mount. Or change it up if you want something slightly different.

Amazon, ebay, ribble, crc, wiggle, jenson, universal, pbk, treefort, modernbike, and dozens more sites sell forks. google will help sort thru a lot of the muck for you.
