First, I think I owe Mark Buswell an apology for questioning his comments about pantagraph items on eBay from seller Casanova9898. Clearly, there's a bit more to this subject than I thought. I am guilty of not paying enough attention to panto'd items; I don't have anything against them, but they rarely seem to make it onto my "wish list."
Second, I just noticed a very interesting Ron Cooper listed on craigslist for the shockingly reasonable asking price of $150:

Located in Walnut Creek, CA. Interesting pictures. Hard to go wrong for that price.
