Do you have a budget? Tapered or straight, 15QR or 9mm, remote lockout, travel....? Kinda have to figure out what you want and start shopping. Not trying to give you a hard time but there are lots of options.
Fox or Rockshox is kinda like the Sram or Shimano question. I was shopping for a fork recently, woulda been fine with a Revelation but a Fox came along at the right price so that's what I bought. Make sure you're doing an "apples to apples" comparison. There are a lot of coil-spring Rockshox products that price out cheaper.
Pricepoint.com has a couple Reba 29'er forks on sale if you want to check those out. I think Bikerbob.com was mentioned also.
