Paypal is great, I use it regularely and have never had a problem. Like teeroy said tho they never recognize the canadian dollar on par so expect to pay an extra 2-3% if buying from the states.
I was looking at ski-doo's website and it seems they have adjusted the canadian prices a bit, if it were me I'd snowcheck a 2012, and the 2.5" track would be a nice addition.
Because Skidoo is greedy? lol. A lot of car companies brought their prices down to match US prices (not all of them), so I don't see why offroad vehicle manufacturers haven't yet. I priced out a brand new Summit in Montana and it was only $8000, for $8k here I'd be lucky to get a 3 year old one...
I was looking at getting a polaris until I started reading about all the problems people have been having in the last few years. Now I'm most likely going to get a M series cat. Everyone I've talked to that owns one loves it
