I know sundown sells B-stock and items that failed QC from time to time in their 'yard-sale' threads, good products for crazy cheap if you can over look minor defects and issues.
I've got unbuilt motors that in my opinion didnt pass inspection i.e. minor scratches in chrome plating or faded. They are unbuilt and could become what ever you want. Throw me a budget.
