Pinball machines won't make you happy. Satisfaction in life makes you happy. I'm satisfied with my life and when I recently purchased my first machine, it increased my satisfaction level which in turn has made me happier (for now) but, that can change. I would never buy something to directly increase happiness. If I buy something I want, it's because I want it. I feel like a NIB satisfaction would fade quickly or even immediately because once something goes wrong you don't have a foundation of repair knowledge to help remedy the problem. Just my 2 cents.
