Interesting post, I have been away from the forums and 'rep scene' for a couple of years and am enjoying rediscovering the oldskool dealers and learning about the new ones.
You have been given some good advice, Trevor is the one to use, it took me a lot of trial and error before I learned this. He will beat any other price (except perhaps Robbie from Aobobuy, who tends to be similar prices but I'm not sure he's a TD here). if you send Trevor a photo or link to what you want, he'll give you his best price, and often its somewhat less than the watch is going for on the bigger dealers websites. - I remember buying an a7750 Daytona from him for $150, Perfect Clones had the same thing marked up to $288
It's worth finding out about each dealer, especially those who don't have a web shop, for instance, you would not want to miss BK's offerings.
Another trusted source which I used to to use heavily was Member Sales on the Forum. Not sure what it's like these days but ordering from Asia used to be drive me round the bend. Nothing beats discovering a classic gem (eurotimez SD for instance) for sale (in your own country) on Member Sales, striking a deal then having the watch arrive in the following days mail. Those were the days.
Better wrap this up its turned into a bit of a book.. Good luck in your
quest and feel free to PM me if you would like any more help.
