I have used this agency twice now and in my experience, both times have been excellent.  I was picked up promptly once and drove the other time.  Both ladies were enthusiastic, quite sexy (esp Sam), and I had a wonderful time.  

Yes, I did tip once, but the total comes out to be reasonable, even for 2+ hour sessions.  The house offers some disadvantages as you might run into other guys and isn't a hotel service, but is a nice place to hang out with the ladies.  Incidentally, I haven't asked if the ladies can meet you at a hotel, but will next time.

The guy who runs Wizdom is a decent guy in my own personal experience.  There may have been past shady things like bait and switch pics, but I can say that the two ladies I saw are as pictured on their site.

Finally, as my two cents from hobbying in TJ for a bit now, price does not predict nor guarantee the level of fun you will have with any lady - even for well-reviewed ones.  Sometimes the chemistry just is or isn't there and I've found that YMMV tremendously. I have used most of the agencies, and aside from rare instances, they have all come through.

Finally, to ask a bit of advice of my own, has anyone had luck with the ladies pictured on Sexytijuana? Particularly Eros?  Pls post or PM me.
