Getting your axle to crown measurement is easy enough:



It is the 483 on this humongous fork. Place a pencil in the fork axle area estimate the CL measure up to where the paint disappears. Exactly the same isn't a big deal, but there are a lot of forks to chose from.

Tange often shows up cheap in some stores. I have one of their forks for a 26er.

Nashbar has a good touring fork, that is very reasonable, but I don't see any sign of it on their site at the moment. It comes and goes with stock sometimes. Their cross fork in steel is really rugged, for discs. It would easily put up with hardware for a front rack, and at 45 dollars is also ideal for someone who wants to try their hand at brazing on their own BOs.

Columbus Tusk is a really nice carbon touring fork kinda pricey, but one can find it at well under 200, at times. I was looking online at Shinny, but they seem to be down at the moment, if they were for real in the first place.

Cheap, good for someone who likes to do a little work:
