Had a somewhat strange encounter with Elton, which is irrelevant here, but I would suggest if you weren't satisfied with the results, talk to one of the Harris'. Elton is their resident vintage bike guru and one of the managers, but he's not a mechanic as far as I know. But only been there once. That said, maybe there were variables in the rims or maybe the wheel builder rushed it, but I'll agree with the sentiment that it is very rewarding to build your own wheels. It does require an investment of course, but if you're somewhat meticulous, take your time and don't skip any steps, you can build wheels as well or better than most shops can, IMO. I considered wheel building a dark, esoteric art, until I tried it. I still believe building very good wheels is an art, but it's not dark or esoteric anymore.
I followed this site and found it to be right on the screws. http://miketechinfo.com/new-tech-wheels-tires.htm
My vintage centering tool and TS-2 are two of the most useful tools I've ever bought.
