I've sucessfully purchased candy machine lots twice from Usedvending.com and both times have been very pleased with the results. Calice is GREAT to deal with. My last deal only worked because of her persistence and understanding. I highly recommend both the site and Calice!
This was our first foray into the vending machine world (we got a mechanical snack/drink combo for our learning center). It has definitely been a learning experience! But, after doing quite a lot of research, we found that Mega-Vending had the best prices and the widest selection. We worked with April who was always supremely responsive both over the phone and on email.
As I sat down with my tools to try to figure out the mechanics of some of our initial problems myself (and I did!).... I felt confident that if I couldn't find the problem, April, or someone in her office would help us out. She stayed with us through the whole process (even though her role was essentially done) and I don't think that you can ask for more in terms of customer service.
If you're thinking about vending machines, they are trickier than they look -- but Mega-Vending was definitely great about the support.
