I called my LBS, here's what he said (I'm rounding numbers up)
Hub 9spd $25
Sprockets rear $40
Derailer $50 Deore LX
new speed shifters set with cables $60
grips $7
Labor to do all $20

Not too bad, I really like the bike, and it's not so flashy that it screams steal me when I park it. One thing I'm going to do after work is put on some wellgo pedals with straps $22. My pedals are plastic.

It works fine now, will it make a noticable difference?
