I'm sure there is, but the shipping cost of a motor from Boston to San Diego won't be all that different from the shipping cost from Portland to San Diego. I've hear the number $150 to ship a motor coast to coast. If that's the cost of quality, and keeping your hands clean, it ain't all that much. :) G.
