I've looked at the Precises a time or two.. actually, someone advised me to get one as my first "mod" a couple years ago but I balked at the price. If I get a mech, I'v kinda got my eye on a Natural. I'm sure if you did list it as a trade for a prov in the classys, you wouldn't have much trouble at all.
The Natural is a nice mech mod for the price. It just needs a little tweaking. Noalox all of the threads, and sand the chrome plating off the screw heads and the bottom post. They are all brass underneath. 5 or 10 minute job.
