.com is king. Everyone recognizes .com's. Many think .info is spam. But they have been decent .info's out there.
Obviousy, .com's cost more than .info's. You could get .info's as low as $0.88 each. Right now, GoDaddy has them .99.
Personally, I use .info's as throwaway domains. I use it, if what I'm doing works then I get the .com, etc. If not just let it expire. You lose $0.99. No big deal. This works great for Christmas btw and PPC. (And another tip, it even sometimes helps because advance users know not to click on .info's while your bread and butter sheep, I mean, customers don't know the difference. And in the end that's who you want to click on your ppc ads.
