I think you're better off with a good 112 than an average 212.
Lighter to cart around, cheaper to try different speakers in. I gig with 112's all the time and they easily hang with a drummer. Often, a 212 throws too far and gets in the way physically, although some of them can be set up vertically as well.
The next question, though, may be 112 closed back or 112 opened back. The closed back will retain more bottom end (better for heavy stuff, chugging, etc) while the open back will disperse sound around the room more and is generally considered a bit nicer for clean 3d-ish and lighter overdriven stuff. These are huge oversimplifications, but that will get your beak wet, at least.
