In the past I've never hesitated in adding a on/off switch to my 50s/60s games. It is so convient to be able to reach under and turn the machine on/off for a quick game. To me if it was tastefully done it seemed like a worthy upgrade.
With my recent addition of Majorettes though I'm holding off. Being a lower production game like this, drilling the bottom panel doesn't seem to be as good an idea as it has in the past. A friend and fellow em collector that is a purist is vehemently opposed to the on/off switch mod. He says he likes to use a power strip. I don't like the idea of crawling under the game every time I want a quick game.
I'm currently just using the kick-off switch to shut the game off. It works but it doesn't really feel right either. Does anyone else use it?
