I guess it comes down to the price, you could give it a go if it was REALLY CHEAP, like almost free. The sides cracked all over the place and welding them isn't an option, they will just crack beside the welds. The track is super soft on the 2017 and will chuck paddles off pretty consistently. No suspension to speak of, it'll eat bearings because the sides are flexing and it needs a big diet. Life and limb will be at risk due to no brakes, like zero. One plus is they are pretty low seat height and turn like crazy with the monorail.
Everybody wants to get started in snow biking on a budget but it rarely pans out that way. I think you need to realistically budget in the 7-10k range in Canada and around 5k minimum in the US. The last thing you are going to want is to slow down your friends in the back country because your POS setup failed. Doubling out on a snow bike sucks, trust me I've done it. Personally I'd walk away from a 2017 Camso new or not, find a 2020 it'll still be cheap if your heart is set on a Camso. Just for reference my 2013 TS had just about as many problems as the Camso did. Kits have come a LONG WAY in the last decade, you get what you pay for.
