Survey Sites: NPD Group and Opinion Outpost

Here are a couple of survey sites currently taking new members. I've joined several sites and fill out surveys when I have a few minutes. It's nice to get some bonus checks in the mail here and there.

I haven't personally tried this one.  I may sign up!

I've tried this site.  It's not one of my favorites, but I've heard others say they like it.  I found I didn't qualify for a lot of the surveys.
