There was one instance that almost made me switch back to gens, just to eliminate the hassle.
About 6 months ago I purchased a rep from one of the collectors. After waiting months for even a communication reply he sent me the tracking number. The watch arrives about 7 days later at my doorstep and its the wrong gd watch. We went back and forth in e-mails with him calling me a liar and saying that I got what I asked for.
This almost pushed me back to saving up and just buying a couple gens. I just didn't want to deal w/ the bs, but there is a happy ending. After ordering from every deal out there I've narrowed my list down to a faithful few who have made me enjoy this hobby again.
