SindyDolls used to be my regular but it's gone way downhill in the last couple of years. Spoke to a girl who used to work there (she's indy now) and she didn't have much good to say about them at all. Luckily for them they're the only agency in Chester (AFAIK) so they can get away with a lot of B.S.
Don't know if I'll ever return. It'll probably be as a very last resort but even then, would sooner go home for a wank. You can get much better VFM elsewhere.
