Every single estate sale I have gone to involving the sale of a serious DIY or profession WW has been attending by hordes of wealthy folks bidding not much less than new for floor tools. Hand tools usually go for pretty cheap. Now clamps, holy cow. I'm thinking of buying a couple hundred clamps, faking my death, then tripling my investment at the estate sale, because that's what I see clamps get bid to at these things. Granted, your typical estate sale bidder is looking for cheap stuff, but spend a Saturday morning in a barn bidding on a 20 year old rusty Grizzly with 50 other guys with 75,000$ pick-ups parked outside with a 50,000$ Harley enclosed tandem axle trailer on the back of every one of them (because they KNOW they're going to be the successful bidder). Wood worker estate sales tend to attract people for whom money is no barrier.
