So my mech quotes me $55 to install chain + sprocket kit...

High/average/ cheap?

 

Not too high. It's an hours worth of work.

 

i'd say that's average

if you can find an air compressor and air gun, it's VERY simple to do it yourself.

 

This is a *DIY* project. Estate, you can do this. :-)

Buy the Stockton Tool chain kit from CycleGear for $39 & it will pay for itself w/ the first job. STOCKTON TOOL COMPANY Parts & Accessories - Chain Breaker and Rivet Tool Kit - Cycle Gear

If you do have your mechanic do this, be sure to double check the flare spec on the master-link pins. <-This is often done incorrectly. Also be sure to check that the flare(s) are not cracked. If they are, the master-link needs to be replaced & redone.
