Here's a tour of a few factories in Shenzhen that I made when I began doing my factory search for my company, http://pavlok.com
For years, I wanted to do business(small quantities at first) in China, but always chicken out when I start to think about the risk of fraud.
Do you know of any service that vets these factories, and is not subject to payoffs? I guess you need to travel there if a big order is on the table.
That said, we are currently A/B testing the buy button on the front page, so 50% of people see the buy button right now.
Also, you can see the full shopping cart page at http://buy.pavlok.com
