Thanks guys

I really love the new technology but Psr3000 is limited of number of keys and key feeling.

However, I will try to test both KBs to see which one is appropriate for me.

One quetions whether SK880 can be updated with new sounds and styles? how's about its keyboard durable?

Actually, I got a rp8 - GEM (I bought around the year 2000')to practice with my arranger RA-30 of Roland (I bought around 1995'). However, my GEM has a problem with the key E3 and I am seeking a Pro technican to fix it. That why I am wondering if I bought SK880 I will encounter the same situation.

Thanks
