PD has indies and a few orgs. Making blanket statements about the quality of girls on PD is just stupid. I've found some real gems there and a few duds. I don't 'take one for the team', so avoid a lot of the total rip offs.
As mentioned, the only thing the reviews on PD give you is some indication of whether they're real or not. Sometimes you'll see statements like "within her limitations' or some shit. That's a good way to weed out GPS girls.
You're going to pay more than k girls though, that's for sure. You have to decide whether it's worth it. I love Ashley Foxx, she's a good place to start. Also
Daisyloveeeee if you're looking for a local latina girl.
