I gig and play quite a bit on my 2000 too. No related problems so far, though I can see how these problems could develop over extended use/time. As I stated before, I initially purchased the PSR2000 as an interim arragner keyboard till the next generation top of the line models arrive. I was surprised to find myself taking the 2000 out even more than my main axe (KN5000). I"m still enjoying both the KN5000 & PSR2000, though I'm keeping my eyes/ears open for the upcoming KN7000.
