The S910 has been pretty solid as far as durability and lack of issues, although, as Diki said, nothing is perfect.

I've been lucky in my district with no problems reported so far, although not everyone calls me when they do have an issue...some call the dealer, so maybe there were some and I didn't learn about them.

Considering how many S910 are sold, having a few with issues is a very small percentage, and some of them have been shipping errors (broken) and not problems with the keyboard itself.

The S900 gave some problems early in production, but customers were looked after quite well, and the S910 seems to have benefited from any mistakes with the former.

I prefer the S910 over the Tyros3, and it's not a price issue with me...I just like a light action, and built in speakers, and the fact the S910 doesn't need a HD.

If I want to talk about price, with the S910 I'm getting a nice combination of T2 (sounds) and T3 (accompaniment engine) at a price roughly a third of a new Tyros3(with speakers)...leaves a nice chunk of change to buy another digital piano (Yamaha CP-5), or even a Prelude(if they add style assembly to the OS).

One thing there is no denying...the S910 is a great bang for the buck, and a very powerful mid-range arranger.
