used from owner,
dealers have thier mark up, factory has even more markup so the dealers can stay competetive.
also once most equipment leaves the building yer taking a 50% hit on value.
so buy from private company or city auction. they will get more then a dealer will give for a trade in and you will pay much less then new.
only downside is used equals unknown maintenance, just go into it with open eyes and a clue as to what yer lookin for
though it seems lately everyone thinks that haggelling is thier middle name...
