Best Snowmobiles?

[ERICbarbaric4]

I am very interested in purchasing a snowmobile (I've rode serveral times now) but have no clue what machines perfrom the best. I'm capable of riding deep snow, groomed trails, performance vehicles or even mountain vehicles. The vehicle will be used in Colorado's Rockies (above 8,000 ft). Money is not a concern for me, just looking for the best snowmobile. It needs to be reliable, but also one that can pull a workload and also endure high performance and sport use. Sorry for making you guys read so much for such a straightfoward question but I am really looking for some good answers! Thanks
