I bought an M12VC about 6 months ago when it was on sale. I haven't used it a lot but it is also a very smooth, fairly powerful router. It has a lower center of gravity that the M12V or V2 so it is a little nicer for handheld jobs where you don't need a plunge. It will still spin large bits but will have to work harder than the 3 1/2 hp models. I didn't get the combo kit since I already had 2 big plungers. I haven't had any problems with any of mine except for one little plastic part on the V2 that is worth $1.37 from Ereplacement Parts.
In the time that I've been on the forum, I really haven't seen much said about any of the Hitachi routers that was bad, at least no more than any other major brand.
