I don't think the PSR2000 is that bad. I play on it every day, doing close to 600 gigs a year. I own two PSR2000s. I have never had any problem with the keys breaking. Here is a list of the problems I have had:
1. Style control buttons wearing out (requiring greater pressure until they cease to work). This has occurred with both keyboards on practically every style control button. Since it was too time consuming to go to a Yamaha tech every time, I had a friend fix this. He has fixed this problem about four times for about $100.
2. A blown internal amp. This took close to three weeks to fix even though I paid $25 for rush repair. Delay was Yamaha's fault.
3. A blown speaker - distorting at high volumes. After this problem was diagnosed, I took the keyboard home with me while they waited for the replacement speaker. It took over two months for the speaker to arrive.
4. Now the speaker that was just repaired rattles at high volumes. I might have my friend look at this as my authorized repair center is 45 minutes away, while I can just drop the keyboard off around the corner for my friend to look at.
5. Once someone who was transporting my keyboard put a large folding table on top of it. This broke a modulation wheel. I haven't had this looked at yet.
Keep in mind that I put a lot of hours in on these keyboards. Nevertheless, I acknowledge that a keyboard made for professionals would probably have less problems.
Playing professionally and owning two of these keyboards, the flimsiness and repair problems isn't that bad. I am seriously considering that when the PSR2100 comes out I will buy two of them and sell only one of my PSR2000s. This way, I will always have a backup keyboard even when one is getting repaired.
I love the harmonizer on the PSR2000. What other keyboard has a really good harmonizer? The Solton. But Soltons also have a bad reputation for shoddy workmanship and weird glitches. And the Tyros. I need the onboard speakers - and it is a bit expensive for me.
I think the PSR2000 is a fantastic keyboard, and there isn't another keyboard that compares in it's price class.
