Good Blues Harmonica Begginer's Method?

[Filipe Marquez]

Hey guys, i wanted to ask you: Does any of you know a good begginer's blues harmonica method?

And also can any of you explain me the different types of harmonica's, how to play scales on them and everything?

I just listened to "It's Only Love" by the ZZ Top and thought it would be nice to buy one and try some blues tunes on it, lol...

Thanks!
