I see ads like these all the time here in Columbia, someone invests a boat load of cash in equipment only to later find out they can't really make a living with all of those snazzy pieces of equipment.
I look around my shop and I doubt that I have more than 3 items that cost over $100 new much less used. My planer the exception and even it was only $200 used.
People love to over estimate their value. As my father once said, and I quote, "I'd like to buy him for what he's worth and sell him for what he thinks he's worth."
Boy howdy! We'd clean up doing that, eh?
I figured it's time to change my signature so hold your breath. This is it.
