check the newspapers. I’ve been to several “Cash Auctions” and the stuff that goes for cheap are big items while smaller “at home” items sell higher than they should.
Reson being, you get a lot of farmers and people looking to use this stuff in their garage. If you’re looking for a welder for example. A little 110V or 220V Single Phase welder can sell for $1K (original price at $1500 for example) while a 220V 3 Phase or 440V Welder will sell for $400 (orign. price at $7K for example)
Just a heads up… deals are good on BIG machinery items, not generally the home stuff.
