SO Close . . . suggestions re: GMT v Sub

[wrandyrice]

I'm so close to pulling the trigger on my first Rolex. Want to be smart about my "first".

Really like the looks of the GMT and the Submariner and have a hard time telling the difference between the two. I imagine they are glaring and I'm just missing it. Any suggestions/strong advocates one way or another?

In the stainless steel models is there much difference between how they hold their value?

Thanks all,

Randy
