Sadly,
I don't think there are many people in their 20's to 40's who see the value in these machines that most of us do. I know we have several exceptions to my broad statement in the hobby; but in general, I believe that they are just that--exceptions. Unfortunately, a lot of us are getting up there in years and starting to think about retirement so there are probably starting to be more sellers than buyers. Slider Bob and I have had this discussion more than a few times. If you are in your 50's or older, you remember when vending machines were in a lot of different places and you probably even used some of the machines that we all collect. I used to love buying candy out of Stoners when I was a kid or sneaking a $0.45 pack of smokes out of the national 9 pull at the gas station even though the machine had the "No sales to minors" sticker on it. At least that was my connection and why I got into the hobby several years back.
Hope that changes because I can't see any of the current vending machines being viewed like the classics that we all love.
