What are the pros and cons of seeing a provider from an agency? In my limited experience I've only seen indep providers.

There are certain advantages with agencies, once your trusted with them, it opens up all the girls that they have working for them, no need to be screened with every single girl and some agencies have 10 or more girls to choose from.
Also if you have an appt. scheduled and something comes up where the lady has to cancel, just call the agency and they will send another girl, no need to look around for a last minute appt.
I've had good luck with a well established agency

Thank you Drea for your insight.  My concern all along is how these ladies are treated by the agency and how much of the donation they get to actually keep.  Also concerned that there is a lot of up sell because of the first concern.  I've had good luck / experiences with indep - think I'll stick with that.

to hobbyists and helps explain the differences between the attitude of some agency ladies and most independent ladies.
