whats the main differences between these 2 machines? I like the 450 Grizz and the big bear 400 4x4 but cant make my mind up between them. They seem to have the same specs, but the price is a few bucks difference. The 350 grizz looks good also, but im worried that might be a tad to small since im upgrading from a 300 4x2 bayou.

any info between these 2 models would be great
