That's a lot. We (wife and I) have had machines for over 25yrs. The first game I bought in 1994 was a Party Zone which I still have today. Probably been through 20 over the years. I am not into turning them over every few months. I tend to take time and really know as much as possible about the game(s) before buying so I end up keeping them.

Newer: may be more reliable and nicer
Older: never know, there are many great ones and many bad

Several good distributors on Pinside, look in the market

I have no opinion on the values, they are what someone is asking or someone may pay. I don't turn games.

The moral here is, we are all different and what I like you may not and vice-versa.

My advise, get a couple affordable used newer you enjoy and go from there.

Best of luck
