Hi all, I'm a teacher in Phoenix and looking to replace the soda machine in our school with one of my own. I'm not looking to make a business out of vending, just something I can manage since I'm there anyway. After researching, it seems the most reliable, least repair, and easiest parts to find in case would lead me to a Dixie Narco 501e. I've been keeping an eye out on craigslist and other possible outlets and am curious, what do you think? Is that probably the best choice?

If so, most of what I see online is from major vending companies selling machine, i.e.

Is it safe to buy these? I'm assuming it's ok, but not having any experience looking through at the mechanics, I'm wondering if they're a company, why would they sell a reliable machine vs. keep it and use it? Thanks all for any input.
