my control panel is level, not sloped and is at 41" from the floor. and it feels great. It is still about 3" lower than my elbows, but I have played it for hours a few times with no discomfort at all. it even works great from my bar stools. I have thought about sloping it slightly to give it a more authentic look, but it is so comfortable now, i'm not sure that is the best thing to do. From the looks of things, my panel is higher than most peoples, but I have found that most real arcade games that I play are too low and sloped too much to be comfortable to play for more than a few minutes.
