Buyer first requests that he delay payment a few days after doing a buy it now because he was out of the country. I agreed. Surprise - when it came time to pay up he says he no longer wants the large 1/2 day long project to package up amplifier. Don't waste time dealing with this scatter brain. 3 rd back out buyer on this amp. Moral of story, don't sell music equipment on ebay without requiring a drug test from bidders.
