Vegas watch dealer recommendations?

[Mccall86]

I'll be flying into Vegas in a couple weeks and wondering if anyone knows of any reputable places that deal in pre-owned Rolex. I've been trying to decide between a couple of 5-digit references for my next watch (16610 vs 16570) and would love to look at them in person/try them on, and perhaps take one home with me if the deal is right. I live in a more rural area so pre-owned Rolex are pretty scarce at the handful of jewelers we have here. Any recommendations would be greatly appreciated!
