eBay has done wonders for the tooling market when it comes to re-sale. Since so many seller are now accessible, it's extremely easy to determine the value of something if you pay attention over time. 10 years ago I would have paid much more for tooling because I'd have to either find it at an auction (and get lucky) or I'd have to find a local guy needing to part with his stuff. The guy who knew what it was worth got top dollar and the guy who didn't got screwed. Now that's averaged out and I'm not convinced that the prices will drop on something like lathe and mill tooling.
As an example - I have somewhat of a Jacob's Super Chuck fetish. It's a little weird, I know, but ever since I became comfortable rebuilding/refreshing them, finding deals became super easy. If I can get a super chuck for about $35, I buy it. As a result of such an awesome buying habit, I have a ridiculous amount of chucks either rebuilt or needing rebuild...here we go.
This pic shows some of the chucks I have, none of the larger regular duty jacob's chucks, only one of the keyless, and the only import I currently have (and it's junk - the jaws are so soft). So in the pic, Three 0's (not Super Chucks but completely useful for smaller bits), five 8 1/2N's, five 11N's, one 14N, one 18N, and one 20N (predominantly for the lathe).
So back to my point. Any of these chucks, when sold locally and/or on Ebay, are worth more than $35. Find a local guy just starting out and he'll pay handsomely for a 3-pack. Anyway, my fixation on chucks shouldn't end up causing me to lose money given how easy I am on them. They should get me all my money back (as long as I buy them at $35).
FYI - I'm telling you all this because I really, really, really don't need to buy any more chucks so please snag them up before I do.
