Are you going horizontal or vertical orientation?
Is this a single player or 2 player bartop?
How big is your bar's top?
I would like to do a 2 player bartop, which is why I thought the 20" mounted horrizontally would be better. But after playing a few games on my computer I am beginning to wonder if I will be too close to the monitor for a 20".
Most of my favorite games are the classics:Donkey Kong, Galaxian, Phoenix, but I do like to mix in some NBA Jam or TMNT also. So I have considered going with a vertical orientation but I worry about having enough room for player 2 when my build changes and my horizontal games looking crappy :-(.
As far as how much room I have. I would prefer something smaller but part of me is saying "The bigger the better!" lol.
I honestly am so torn. :-( Anyone else have experience with 20" or 17".
