I'm currently into coin op arcade games, soda machines, candy machines, juke boxes, etc... I rebuild/repair all my machines. Currently in my basement, I have a Donkey Kong, Robotron, Tempest, Time Pilot, Pole Position II, Merit Megatouch bartop machine, poker machine and an old coke machine (beer machine). On the basement tv, I have an Intellivision, Nintendo, N64, Dreamcast plus a few newer systems. In my garage I have a Baseball arcade game that is kinda beat up but its a lot of fun, so the garage it will probably stay. I've also got a Seeburg Juke in pieces in the garage right now as well as another coke (beer) machine. I've got 2 boys and they both love the games as do their friends.. Makes for some interesting parties.. I coach 2-3 sports a year for each of my boys as well..
We are also into atv's. The 3 of us have them, but don't get much use anymore. The boys have outgrown them and last time I was out I fell on my ass so bad I couldn't sit for a week. Almost 6months later and it still hurts.
Before all that, I was into Home Theater. My buddy owns a HT company, so it became real easy to get set up with good equipment. Now the PJ gets used for Xbox, and Wii mostly.
I also like to hack things.. I modded my original xbox, satellite recievers, arcade games, whatever I can find, I'll make it better.
My wife just shakes her head. As long as my hobbies are relatively self supporting, I don't get too much grief. I get rid of some old junk to buy some different junk. My nickname with friends and family has become Fred Sandford.
