On the odd occasion when I've thought about going with 12s, the ideal setup for me would be a good pre with a Berg IP112 (I've tried one of these, it's stunning for its size) and then an EX112 added for bigger gigs. The cost and the fact that I like my current rig so much (MB 210 +115) has stopped me so far, thankfully. 
But if didn't like what I already have, this would be the way I'd go, for sure.
