You can take your sled to any dealer for warranty work, you don't have to take it back to the place you bought it from.
Umm, yeah that's true..... unless of course you want it done right and in a timely fashion.
Every dealer sells sleds but not all dealers have good service departments or staff who are willing to go the extra mile for you. I have a big local dealer and yes they will give me a lower snowcheck price but I use a small dealer an hour away because they know me by name and when I want to say 'jump' they say ' how high?'. I don't abuse that privilege and I am always super nice to everybody that works there because I want them to
want to work on my stuff. The payoff is that over the holidays I had two older sleds that broke down while we were at our cabin, I hauled them down the mountain, told them I had a cabin full of guests and could they please get them done asap and I was picking them up the next morning. You can't put a price on that. Service trumps price every day!
If you have to pay a little extra to use a dealer you know and trust, so be it.
And when I snowchecked last year I did exactly what someone mentioned earlier - I went to the large local dealer, got their best price, took it to my dealer and asked him to match it. he got within $500 and we called it good - worth every penny in my mind.
