Living in Canada your going to pay through the nose for one, don't really matter which one. If your going to the fall gathering I would be on the look out for one down there, you just might save yourself a few bucks.
I bought my Sedona Digitally Controlled Food Dehydrator (SD-9000) through amazon.com and of course paid more than someone living in the U.S.
I have never owned a dehydrator before so I can not compare it to the others mentioned but I have used it pretty much every week since I got it and love it. I do a lot of dried fruits for the kid and lately I been doing tomatoes as I have so many of them. I have done lots of jerky but never snack sticks but the jerky has always come out fantastic. The thing about dehydrators is you either love them or not, so I would go through kijiji.ca and see if you can get a good used one.
Don't know if this guy will convince you to buy a Sedona Dehydrator but he is fun to watch
