I'd be afraid to buy a bridge in Manhattan right now. It might be rusty.

I think that by the time you run the keyboard through the pa, add crowd noise, etc., the sounds on virtually every current keyboard are more than adequate.
If you get into a studio situation, with intricate recording of tracks, it would be a different story. Still it would take a fairly critical ear to find fault.
I'm still pleasing people with Roland E50 from time to time.
