When I am setting up in advance, I usually look for providers on P411. Then I'll check TER for ratings/reviews and then book through P411 so my screening info is easily accessible. I think it makes things easier for the provider since I'm not having them click through a bunch of links or copy and paste into another site.  

My experiences with BP are never as good as the appointments I've booked using P411/TER.

I would rather stay here than go anywhere else! P411 is second,  but BP brings a lot of BS that don't play the way I like! I enjoy the respectful demeanor of the friends I meet here! This is the only place I really make sure I post every week

I will look at sites like EROS and BP but without confirmation of their legitimacy from elsewhere I won't call based off of just an ad.

BP almost exclusively.  Right or wrong, that's my M.O.
