Based on off my own experiences and what the OP is after I'd say 219 Croydon is worth a visit.

I haven't been to all the ones here but my own experiences are

219 Croydon - 200/h
42 Gladesville - 250/h (for Caucasian)
Cleopatras - 340/h
Liaisons - 350/h
Stiletto - 400/h (+50 for kissing)

Hope it helps
