I just concluded a flawless deal with Vintage Navitimer aka Kevin. Bought a blue Sumo. The experience was terrific. he was honest, communicative, and the watch was "as described". No problems at all, and I'd happily deal with him again.
I got near-scammed only a month ago when I tried to sell my first watch, and a guy in Toronto tried to stick it to me. That left a very bad taste in my mouth (and a determination to avoid OCONUS deals, and also to avoid Paypa, where possible). Happily, people like Kevin also exist and they restore my faith in my fellow-human-being.
