Sorry to hear that lee. Unfortunately we dont know anything about a buyer until he buys. I had a situation a while back when I sold a 346xp. The guy was demanding i pay his repair bill. Yeah, he brought it to his shop and they found a problem. the adjustable oiler was "set too low" so they charged him $20 to adjust it. Now, if this was true and he believed it, he shouldnt go near a saw. I explained to him that he had been taken and even tried to explain how the oiler worked. He persisted so I told him I would not in fact give him one cent and that the next step would be reporting him. He never left any feedback so I considered it a win for me. But not worth the aggravation.
Half the time people on ebay don't leave feedback when they're happy with the deal. I rarely get a complaint but don't get any feedback, good or bad, on lots of sales.
