Looking to buy my first Rolex

[RolexEnthusiastMD]

Hey guys, Rolex newbie here. I'm Currently shopping for my first Rolex Timepiece. I have narrowed my search down to 2 watches:
TT Rolex Datejust 116233 Black sunbeam dial
TT Rolex Datejust 116233 Slate Sunbeam dial

I'm looking to purchase a pre-owned perfect condition piece instead of a brand new one for 10,900 plus tax. I've went to some rolex stores near me and none of them have the sunbeam versions of the 116233. Apparently rolex discontinued these badboys. I however think they look amazing. What is your opinion on this? There is an ebay seller (LuxUrTime) who is selling a silver sunbeam dial in pristine condition for 6750$ which I am considering getting. Please chime since you're all much more versed in rolex than I am so far. Thanks so much guys.
