Megadeth are certainly on the list here, although they had a long stagnant period. I liked System, and just picked up the DVD and Abominations. The new disk puts Megadeth back to old form for sure and the Dover brothers are the injection the band needed (from Eidolon - Canadian band with a few good albums to their credit and the guitar player had a stint with King Diamond to boot).
Don't sell Dave short on his playing, never seen em live but after seeing the DVD he does a good few solos that I always assumed were "the other guy".
