I'd have to say be sure you are aware of the difference in body shape/size and how it affects the tone correspondingly before you purchase. Personally, I would gravitate to the '97 422r just because I would prefer an older guitar than a newer one BUT the 314 with blackwood could be a very interesting score as well. In general terms the 314 would have a "bigger, fuller" sound and the 422 would occupy a more limited "sonic space". The Grand Concert shape is preferred by many since it is more limited and lets other instruments come through the mix better, esp. vocals. If you are more interested in the guitar's voice only, say for strumming, the Grand Auditorium may be better choice since they tend to have a fuller sound all around. Hope that helps a bit.
