Like an earlier post about the haircutter. I have never been injuried by a bad haircut, but I could sure end up dead if bad mechanic worked on my bike.
I would like to see certification by the bike manufacturers that they only sold to shops that were "factory certified," and employed only trained and certified mechanics. I think this would be a step in making "wrenches" a bit more professional, and not just college kids looking for a discount on bike parts.
Would I pay more for this as a consumer? Well lets just say I was 300 miles from home on a week long tour and something broke on my bike, and there were two shops listed in the local yellow pages. Joes Bait Tackle and Bike repairs, and Bob's Bikes Cannondale & Giant certified. Who would you choose?

In my trade I can not purchase "Corian" to make a counter top unless I have taken and passed the course DuPont requires, and this is just material to make a counter top out of. Never seen an injury due to a failed counter top. I also can not install it in your house unless I am liscensed by the the state, bonded, and insured.

To the Rev, I beleive that there are a lot of people out there that do know what they are doing, but how would I know, you knew anything about bikes, if I walked into your shop with a busted bike because you were the closet one I could find.
