Here are the agencies that I've used over the past couple of years. I'll list 'pros' and 'cons' but to be honest the 'cons' are hardly shots at the agencies as much as they are limitations (read on and this will make some sense). I continue to use each of these agencies with great results and confidence.
BAD:
PROS: great agency. THE agency to use to satisfy my Asian taste. Amber is GREAT and communicates professionally and consistently.
CONS: Quick turn over of the girls and they rarely return so if you find an 'ATF' it can be a fleeting affair. Also, for a 60 minute appt the tendency is for a 1 pop adventure. Not really an issue as I know this going in and plan accordingly
RSG:
PROS: great agency. LOTS of ladies to choose from. Most of the top performers that are visitors make frequent return trips. Jill and staff are top-notch. Great value. Many of my ATF's are at or started with RSG.
CONS: The only thing that I can think of is that they do not service the downtown area. Not a big deal as there are plenty of indies and agencies that cover the city.
Nina's Genuine Diamonds:
PROS: Nina is super responsive. I've only seen one girl from her agency since she's returned to the area but that one lady is at the top of my list.
CONS: Limited 'stable' and therefore limited geographic coverage.
BI:
PROS: Lots of young talent and a fairly consistent group of repeat visitors to the area. The vast majority of the girls I've met through them are 8+ to 10 in the looks area.
CONS: I'm still disappointed at the rate increase that took place a couple of years back. It seemed like a big jump to me (+$50) and now I have to REALLY interested in a girl from this agency before I book. Part of the reason for my hesitation is that I've found the girls performances rather 'hit or miss'.
Flawless:
PROS: They send girls to Boston on a fairly regular basis. Most tend to be top notch lookers and performers.
CONS: Their prices for the girls vary and I can't find any rhyme nor reason for the variations. I'm guessing it's what each girl has agreed to but some of the girls I'd like to see seem to be priced higher than what I'd like to pay for the services rendered.
There are plenty of others out there that I've either never used or just used once that I don't think it would be fair to comment on
