How to add a Facebook page like button on my blog?

[Sonia]

Hello everyone
I have a blog on blogger.com. Also, I have made a facebook page for my blog. I want to add a 'LIKE' button in my blog so that they could like my Facebook page, without getting to go on Facebook.
I mean, a new window shouldn't open; just that the user clicks on like and my fans increase from 100 to 101.
Links or details are welcome
I already have facebook badge or post like but not facebook page like. so pls help

Thanks
Dear Andy,
I have already tried the top 3 links. And they add a social plugin to like the page and open in another site. Guess you did not get my question properly
Never mind
