Well, here's my list:
1. Stevie Ray Vaughan (this guy was just insane)
2. Pink Floyd's David Gilmour (technically not all that masterful.. but his melodic solos are just incredible)
3. Black Sabbath's Tony Iommi (from reading the last few articles, I know I don't have to tell why)
4. Dire Straits' Mark Knopfler (Nobody fingerpicks like this guy)
5. Øystein Sunde (I bet most of you haven't heard of him :-)
On the other hand (I know, I'm gonna get flamed for this one), I totally disagree with those of you who claim that Hendrix was a great guitar player. Okay, he was innovative and creative... but in my opinion, all he ever did was come up with a bunch of tricks that people had never heard before... I mean, anyone could stand on the stage, making weird noises with their guitar, if they just had enough distortion and other cool effects... :-P
