I have both. 5 video arcades, 2 video pokers, 3 slots, and just picked up a gumball machine. Still would like to find a soda machine, jukebox, and a coin pusher for the basement bar.
Both. Right now I have 2 upright vids, 1 em pin, and 1 candy vending machine. The candy machine has 3 canisters with separate coin mechs; 1 section designed for gumballs and 2 for bulk candy (1 filled with peanut M&M's and 1 filled with cashews).
I don't really have the space for another full sized game, but could probably find space for a smaller novelty or tabletop coin op machine if the opportunity presented itself.
