I have an old standard 19 inch monitor in my cabinet.  It has some burn in and I'm afraid it is going to die on me.  I'm looking around a bit at monitors, but I'm completely bewildered by the options.  I see a bunch of different Wells-Gardner models that to me look exactly the same.  What are the differences and how would one go about choosing a monitor?  Is Wells-Gardner the way to go or are there other options for a good price?  I wouldn't mind going to a higher resolution just so I have the option to run some of those games, but don't want to pay an arm and a leg.
