Buy a Yamaha and thank me later.
Every brand has well performing sleds, but think of Polaris, Ski Doo, and Arctic Cat like you do European motorcycles... fast, great performance, and shitty reliability.
When Suzuki made Arctic Cats engines they were much better with reliability, not the case now. Polaris was decent until the engine manufacturing went to Mexico. Ski Doo is the better of the three in my experience, but things have changed over the years.
