I'd say your both right. (can't post links yet, Mares site lists it as Rover 2 and Rover 12.by the way its not called rover 2 its rover 12!
Any way I'm looking at these at my LDS, salesman/owner says this model replaces the Ranger line with a few improvements. It was pretty busy there so I didn't get a chance to ask what has been changed.
Would like to hear more as I'm looking for a entry level setup.
