One of our auction goers bought 3 units his first auction. He spent $300 and came out with a profit of $500. There were air tanks and the like for welding, still full (glad they didn't explode) in one. Those made him about $400 total. One unit had over $30,000 in crystal from germany, which he donated to the local churches and rescue missions before realizing the value. He was very pleased that he made out like a bandit. Comes to every one now and buys at least one unit.
