I rode a 2010 RMK 600 a year ago, and it was the biggest POS I have ridden for quite some time. Granted, it was a rental that another rider in our group had. He was stuck all the time and couldn't climb to save his biscuits. He had limited mountain experience, so I blamed it on him initially. I traded sleds with him for 10 minutes or so, and I could not believe how underpowered it was, and how crappy it handled. Spend the extra money and get a Pro. They are the deal.
