next time be interesting to get a couple of others folks to do it at the same time, from different parts of the country, from the same vendors.

then when I retire and move someplace new, I can figure out optimal location to get parts as fast as possible

Oh, and I do have to point out the entire experiment is somewhat flawed, since Steve Young/PBR was not included. That alone would have provided some interesting data, since "updates" from Steve work a little bit different than most vendors.
