Hi Everyone, I am trying to get one of my units serviced. I found an ad on ebay posted by hallofivintage. http://www.ebay.com/itm/26234511515...1&exe=13926&ext=35632&sojTags=exe=exe,ext=ext The thing is he requested the entire bill be paid even before the unit is received by him. Also the ad states $675 but when I contacted him the price became $850 and I am not sure if I should do it. Is it a normal practices for this kind of things?
