Some first time purchase questions

[Brushpup]

Well, I will post this again and hope it makes it this time.

I first want to say thanks for the warm welcome over at the new guy forum. I am aout 18 months out from my First Rolex and have lots of questions for everyone. First, what do's or dont's could any of you share with me? Positives, negatives, lessons learned etc. I am going to an AD since I want a new watch, so thanks you guys for re-enforcing that with me. I want the real deal, and I sure dont know how to deal in second hand Rolex.

I have thought until recently that only a SUB D, SD, or DJ in steel would do, but I am actually considering a "lesser" model now Like the OD or AK. Either would be more practical for my budget, but I don't wan't cost (within reason) to be the main driver. Honestly though, the smaller watches have appeal to me and certainly (I think) look better with my smallish wrists. I am sure I would enjoy any of these models very much though. I know that disadvantages to the less expensive models will be largely a matter of taste/preference however, but I wonder about movement quality, bracelet quality, waterproof-ness etc... I also wonder,do Ad's deal on these models much or at all? Do they Deal on Subs,SD's, or DJ's?? We have two AD's here, and a couple more within two hours drive. Should I shop them all? Call them?
I would be grateful for any and all input.

Thanks in advance,
Patrick
