I am looking to purchase a couple of used snack machines to add to my route. Currently have 1800 machines. I just want a good solid machine with as few breakdowns as possible. I know all machines break and have issues. I've been looking at AMS, AP, Crane and rowe. Leaning more toward AMS and AP, are they solid machines? Are there machines I should avoid? I know to avoid Sega and Genesis. What would you buy? Thanks
