The Volks Folks have a very good reputation with the owners of Bug Stuff, Online Air Cooled Parts, and West Cost Metric. I don't have any of their numbers or email addresses handy, but when you contact them, ask for Jack at Bug Stuff, Tony at Online Air Cooled Parts, or Tod at West Coast Metric . . . tell them you're a member of the Scenic City Volks Folks in Chattanooga.
For the big west coast dealers, I've had the best luck with CIP1.com.
