I really enjoy fixing, restoring them more than playing them I have noticed lately.  I probally only play mine once a week I suppose.  But I got really excited when a mate told me he was looking to buy a game, then I had to orgainse everything for him, dealing with seller, transport, parts, repairs and a quick tidy up.  That stuff for me is exciting, playing the first games when a pin is running at its optimum is where it is at for me.
I still enjoy them and I find I get high scores more often after a long period of not playing but really find restorations and problem solving a great outlet.
