^ I don't know of any clips, unfortunately.
Also, I'd say the 5150 is a better amp. Not amazingly versatile, but what it does well, it does very well (and it probably does the rock thing better than the randall, and definitely does metal better). The randall is pretty much a budget amp.
I'm not sure about a VJ- that'll cover classic rock pretty well, not so much harder, more modern rock (eg 80's), which the randall doesn't do too well either.
I'd say 5150, seeing as how you're in the states, as they're pretty good value. That being said, twilight odyssey had two which both broke on him, you might want to see what he has to say about them.
