If you don't trust your LBS - or even if you do - you can do a lot worse than grabbing one of these:

Having just spent a four-figure sum replacing the drivetrain of my MTB  after chain wear took over, I invested in one. Now I will decide the timing and nature of my drivetrain (and bike) replacements.
They're cheap. Should pay for itself at the first chain replacement (either by getting more life out of a chain that might have been retired prematurely, or by saving cassette and rings from being trashed).
 It needed new chain, cassette and rings. And crankarms on which to attach the rings. And BB, which is now kind of integral with the BB. And new shifters with the correct number of clicks to shift on the new cassette (since high-end 8-speed cassettes are now stocked in the shelf below hens' teeth). So I paid a tiny bit more and got a free frame, fork, brakeset and wheelset as part of the deal
