If you are in for the long term, stick to .coms.......and go for .nets if you really want specific keywords and the .com is already taken.......down the road, you will be happy to have those and get good money for them! (you will have a hard time selling a .info for a good price unless it's a VERY good name)
That's the way I do it, and do not proclaim myself a domain guru, but I know that my portfolio will be worth good money when I decide to take a long and good retirement.
