My advice before tossing any money to any dealer is: pause!
There are dozens, if not hundreds of variables with subs. Movement, pearl, bezel material, bezel color, crystal material, anti reflective coating, Cyclopes, dial, dial color, rehault, lume... The list goes on! I recommend going out and looking for the perfect GEN sub you like THEN shop around for the rep closest to it! A gen sub from 1970 will look NOTHING like a gen sub from 2011.
After that, go search for the black/blue/green/two-tone sub you want and start nitpicking the flaws you are willing to live with. In the end, you may save yourself $100-200 just because of minor flaws you will never notice. Doing all this work found me a few amazing watches... that aren't subs!
Footnote: if the words bezel, dial, and rehault mean nothing to you, take some time to learn about them. Also learn about the movement options.
