who is a good Canon parts vendor source?

[Sam Tofu]

We are a Ricoh, Kyocera Dealer/ Service Company. One of our larger clients also has a number of IR Canons and wants us to service them. We have techs with Canon background but not a good source for Canon parts.
We have a wholesale account with Precision so can get some there but looking for other vendors.
Any links. known dependable sellers would be most appreciated!
TIA
