I don't trade much, so I don't really have a dog in this fight, but I would say *current* retail. When evaluating the price of a potential purchase, it seems like the most salient comparison is what I would presently have to pay new, not what I could have paid in the past (and no longer can). If the retail price increased gradually over a period of years, the asking price should reflect age; if there is a sudden large increase (Manley?) the seller got lucky, and that's life.
IMHO, of course.
