Auctions are dangerous - I went to one recently and ended up owning three self-propelled concrete buggies. And, I'm not in the concrete business and don't intend to be. But the prices were right. The ride-on unit pictured in the bed of the pickup retails for nearly ten grand and I paid only one. The two walk-behind units at the front of the trailer were an even bigger bargain. Now, all I have to do is re-sell them at a profit.
