If Asians are your thing....
I've only ever went with the adult work Philippine girls because they are really cheap compared to other websites at only a pounds a minute sometimes. Camera quality is shit, and they just generally look sweaty and miserable.
If you're wanting to spend around £50-£100 I suggest
External Link/Members Only. You better lurk a bit and wait for a girl to turn blue and see if her viewer count goes up to about 5 and them jump on and take a peek.
Normally you might find the ultra young looking ones who look like they just turned 18 are just gonna hang around for a day and bait you to go private and then they will just ignore you when you try and instruct them to do anything. Best to try and find one that looks like she's had her confidence utterly destroyed by constant stream people coming into her room and leaving again or one thats pacing about waving a dildo about trying to get a customer.
