Where are you looking for buying leads?

[Sophia_Asian]

Hi!
What are the best sites / search engines / databases to find buyers of components and subcontract manufacturing?
I found some of them - business.com, alibaba.com, tradikey.com.
Before I open paid account - is it really working? Di you find some good leads there?
Thanks
Sophia
