About 2 years ago I was lookin to get into hendrix myself. I ended up buying Experience Hendrix: The Best of Jimi Hendrix for pretty cheap at some record store. Basically it has 20 of his best tracks. I think it's pretty cool. It's real cheap now. Here's a link to it on amazon...if ur'e interested in the tracks on it.
