If you're using godaddy you can get great .com .net and .org EMD
I've ranked many sites for very easy to medium competitive keywords and I've found my .com to rank faster than my .info in the same niche pursuing the same keyword. Although the backlinking was a bit different, the number of backlinks was slightly higher for .info to be able to climb the ranks. Since info domains are cheap and there's a ton of them, it looks as if the search enigines (google in my experience) tends to rank/index .com's faster.
My niche was in airplane simulation FYI
Good luck!
