...the bike co-op here in Sacramento has one. I bought it for them when I worked there.
for some reason most of the shops in town did not choose to do this repair, so it seemed like an obvious choice.
We used to do the repair for customers at the cost of the threadsert, which was six or eight bucks at the time. Those suckers are pricey.
Unless it's a pretty special crank, it's usually not worth the hassle of shipping it around.
