Hi RC and welcome. Great choice of first rep.
Depends mostly where you are based, if in the EU or UK (Deliberate distinction made!!) the safest way to buy is from Chris at EuroTimez or PT, both are trusted dealers here, but any trusted dealer will be able to help in your quest.
Do some reading, find out what flaws the rep has and ask the dealer to pay special attention to these areas and to let you have a photo or two of the watch he will be sending to you before he ships. That way you will not have any unexpected disappointments.
Good luck.
