Help, which Rolex to get?!?

[submaniac]

I have recently been left some money by my Grandfather in his will (eternally grateful to him!!) and was thinking of treating myself to (a much lusted after for many years) world famous Rolex.

I love the subs but have currently fallen in love with the GMT II. Although I'm not sure I'd be comfortable with something that size and expensive on my wrist! Although i'm sure I'd get used to it!!

Please help! is there anyone here who has spent ages agonising over their first Rolex purchase?

Thanks
