Like doughslingers said it is risky to put games in storage. I moved from a college rental house about 14 years ago. I put my games in storage (12 arcade games no pins) and a bum that was living in the unit a couple down from mine burned the damn thing down. I had some great buys like an original gauntlet for 100 bucks and all the classics. I never could find replacements for the prices I had hunted for. Sell a couple and take that 65 dollars every month and put in an envelope along with the money you sold them for. When the time is right for more pins you will have a nice little nest egg saved up just for them.

Also everyone has their opinion and so I will throw mine in as well. All relationships have to have compromises. If not then welcome to hell. You have a right to tell/ask things of your wife regarding her behavior and decisions and she as well with you. If at the end of the day she is not telling you to get rid of all your machines just out of the living room then that would seem reasonable. If they could fit in your game room it sounds like she would not have any problem with that. Would you let your wife build a shoe rack on the living room wall for more shoes?
