I've got a 95 Polaris 425. It's a good machine. Me and my dad have had a big buck on it that probably weighed in at 190lbs field dressed and both of us on it. It was squattin like crazy, but it still had plenty of power.
A friend of ours has the Sportsmen 500. Another great bike and even more power. I like that his is shaft driven too.
The only beef I have with the Polaris bikes are how beefy they are. They are definitely a work bike and it takes both arms to turn those handlebars at a stand still. I can't really compare them to anything though because I haven't ridden anything else.
Another plus, they are made right here in the USA.
Buy ya something that doesn't end in a vowel.
