Bernie Mikkelsen (Alameda, CA) did it for 2 of my forks, one went from threaded to threadless and his work is perfect...he was charging about $65, but I heard his price has gone up. Ideal guy for gaucho777 since he's in Berkeley, but those of you outside the SF Bayarea will have to find a local framebuilder who does as good a job as Bernie (or ship it to him).
