Does anyone use a yamaha hammer action keyboard? I've been using the P-120 for a few years and it seems that every 4-6 months I have to get a key repaired bevause the key will stay depressed as though it's stuck though the keyboard repair people tell me it's a spring problem. Do I need to dump my Yammy and go to a Roland SD-700.

Anyone else have key problems with their Yamaha's. If simply carting a keyboard through normal road conditions can cause this then it's not a very roadworthy keyboard action.

I'm at the end of the rope with this. Can anyone shed some light on this or offer a suggestion?
