Any recommendations on a provider who provides a BBBJ comparable to the ones provided by the retired Amber Reese?

She left the game at the top of her profession.

assuming you rate her among the best, here are a few others:  Lizzy, Red (formerly Simone-X), Robin, DC Simone and Anik -- not necessarily in that order.  As a connoisseur of that particular sort of thing, I'm pretty picky.  All of the above -- and a few more -- certainly fit into my own top tier.

Never met Amber but Anik,CJ and Paris Devill would provide that service.

Yes I do miss Amber!

Do you mean wenchlizzie?
