Barry Scott, he announced on the CR list that he is going to do his own site, so my guess is probably drift away from ebay. Like Hilary Stone has.
Barry does seem to find significant stores of parts in "lots". Indeed his prices are dear, I think the folk who buy are those who want NOS which is what he mostly sells and they also want it now, or are tired of waiting and watching. I do often find his Sale prices still absurd.
