I admit to being frustrated by (one or two people at) Harris occasionally but I still patronize the place. (I live only a few miles away.) I'm not sure which one there is Elton, but I do trust their mechanics to know what they are doing. They don't have much more C&V knowledge than any other shop but they do seem to want to be helpful rather than dismissive, and their inventory is pretty good.

Re wheels, I recently had an unsatisfactory experience with wheels hand-built elsewhere. I finally took them to Harris, and their guy, who I believe was the shop foreman, did a nice job building what I wanted in the first place. I've taken other stuff there for work and come away happy. Since then though I've just built whatever I needed myself.

Disclaimer - I worked there one summer long ago assembling bikes. I had mixed feelings about a few things then but I'm still willing to forgive.
