I've used them in the past.  They were ok but a little difficult to deal with.  Beside the info they wanted, the phones always seemed busy when I tried to call.  I remember going to an hotel and having to call them to get the room number and waiting about 30 minutes to get through.  And then the girl was bitchy about the fact that I was late.

I've worked with many agencies over the years (many now gone) and TLC has surpassed them all in level of service.  So, I've been pretty much using them exclusively for the past several years for porn star dates.  But, if BM has a lady available that TLC doesn't, I wouldn't hesitate to use them if I really wanted to see that lady.
