Hardinge tooling on Phoenix,AZ Clraigslist

Saw this add for Hardinge threading stuff on the local Craigslist. I do know this guy but no $$ interest in this deal.Has some other Hardinge stuff also check his other adds.
Lot of 19 Hardinge Precision Threading Lead Screw and Follower $570.00 - tools - by owner - sale

He's asking a fairly high price, but not ridiculously high, for that lot. First, if you have the Hardinge HC with threading attachment that these work with, you probably have already most of the common sizes in that lot. Second, $30 for one master/follower pair is on the high side of what I paid for each pair I bought on eBay. (Years ago, no idea what the current prices there are now.)

If I were in the seller's shoes, I would separate out the uncommon sizes (the metric, the left hand, maybe the pitches under 13TPI) and put them up for sale individually at about $50 a set in a wider market than a local Craigslist. The common sizes I'd lump together in a lot and let go for $15 or $20 a set, hoping to snage a new HC owner without any tooling for the threading attachment.
