I realize that is's not a 12" but have you looked at the cutting capacities of the 10" Makita LS1013? Its maximum cutting capacities rank right up there with alot of the 12" SCMS's. FIL has one and IMO it's one sweet saw. Another plus is the OEM blade that comes with it produces mirror smooth cuts so there's no need to buy an after market blade. Sorry for sorta hijacking your question but leaving this SCMS off the list of possibles would be a shame considering the amount of money you are about to spend.
