First, an apology for having lost my Pierce Piano Atlas. My research online indicates that the PG-185 was designed by Pramberger, and therefore must be a 1995 or later model. However, another tech dated this piano with serial #G054761 as a 1990. Furthermore, is this model significantly better than the G series? Is this a good piano? I know someone who may want to buy it, but it's in another city 3hours away so I don't want to just hop over there just yet. Thanks,
