Anyone know of a survey/testing/product testing company such as TestingTime?

I’m wondering if there’s any companies that operate in the same Way as TestingTime. Sign up, wait, and get emailed trials (up to £50, in person or on skype) surveys (Usually around £4 online). They pay so much because you barely qualify for any of them - so I’m trying to find more companies that email you when you can sign up for a test.

Anyone know of anymore companies that do this sort of thing?
