I'm looking for ideas on using the web to generate primary data for a
market research project. I expect the responder to know the
distinction between primary & secondary data in this context.

We have invented a new ergonomic mouse, and basically I want to know:

1. Is anybody going to buy our mouse? i.e. is there a market for our
specific mouse?
2. How much people would pay for this ergonomic mouse 
3. Which of the 10 names we have in mind will be best

Please point to actual examples (maybe with blogs, websites, survey
sites, list providers, etc.)
