My LBS here in Holland, MI ( Cross Country Cycle ) is great. Always willing to help and never pushy. I happened to mention one day that I wanted to learn how to wrench on my own bike when I was dropping it off for a tune-up and Nate the mechanic took me the through the tune-up step by step. I also asked them if they could order a PlanetBike Blinky Superflash a while back. They ordered a whole case and they now sell them cheaper than I could get one from PlanetBike for!

Nashbar has been great. Awesome prices and fast shipping.

I have also had great success with Amazon store front Niagara Cycle Works
