Need driveline/axle shop near B-water

[mtnhopper1]

I have a nasty vibration at 60+ in the driveline of my recently-purchased '02 s-10, and I can't seem to track it down. I suspect the driveshaft is out of balance (it is aftermarket 1-piece aluminium), but it may be something else, too.

PM me if you know of a shop with driveline/axle faclities that could check my driveshaft for balance.

*I've never used either place, so I don't know about their quality of work. I just found them with a google search.
