Advice for first Rolex Buy please help.

[ASimon0311]

I recently have decided to buy My first Rolex of my own and have settled on a submariner. I wear the Daytona 116523 two tone my father left me every day but it turns quite a few heads and some people look at it and I have to walk a little faster if you know what I mean. I have decided to treat myself and have started looking at subs. Should I buy vintage or new? Which reference numbers are the best and most collectible? Are the new ceramic Bezels really the huge improvement over the aluminum as they advertise? Where should I get one given dealers are always dry? Thanks all!
