beerbarrel, since you are new to the hobby I have some advice.
Before you put money into the monitor make sure its bright, clear, crisp & free of burn in. If it has any issues you may want to consider replacing it with something else.
FYI: The larger your monitor the better vertical games will look, you can always play my favorite game "Pythagorean theorem" to determine the area of a vert screen vs the effective area of a vert game on a horizontal screen. You may drive yourself crazy doing that however

& thats not really the formula to use anyway, I was trying to be funny....its actually easier to figure out than that.
IMHO dont worry about the "purist" aspect either, its called emulation for a reason, because...its not even the .....um I better be quiet....just use whatever you want be it a TV, LCD or PC tube....its all good
