Best to buy in the USA or England?

[Bushbaby]

Hi Everybody.

I'm new to this forum and am hoping for some advice.

I've decided I can no longer live without a Rolex. At the risk of upsetting a few people, I'll be going for a new GMT Master II. It was the Master or the Sub but the Master won out in the end. I haven't quite decided between the Steel or the Bi-Metal model yet (black dial). Any thoughts on this choice would be appreciated.

My main question is I'll be going out to Florida this Christmas with my family. Is it worth waiting until then before I buy? I'm not sure whether the cost will be the same and whether there will be more choice. I've already seen some watches on USA sites that I have never seen in England. I saw a Black Carbon Fibre Master the other day. I assume it was a genuine Rolex? Any other factors that I should consider?

Thanks for your help.
