What should I offer for pair of new Blackwell 100s?

Not sure if this should be in classifieds. If so, apologies.

A shop in my area has a new pair of Blackwell 100s that have been hanging on the wall for some time. Given that Blackwell is going out of business, what do you think is a fair price to offer? I don’t want to gouge the shop, but the lack of warranty and spare parts support definitely affects things. I was planning on picking up a Jet Disc and Jet 9 combo, but it occurred to me that a good deal could be had here and the shop would probably like to turn over the inventory.

Thanks for the advice.

Watch and see what these end up selling for: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=320332515895

not sure on price, but if you get the chance they are awesome wheels.
