I'd go MVP2 myself. Price hunting I'd shoot for 35$ or less on the big upcoming sale days. Just use an adapter if you are worried about the threading or pin issues. This goes for anything you buy.
Sure, the MVP3 is going to come out, but can't be sure when or if it will be as good as the hype. An MVP2 will probably not let you down though, it's been through a long time of testing and use by so many.
