O8,
I apologize - I thought that quote was from you. My expertise lies in performing full time at a variety of venues about 320-350 times a year. This is why size, weight, quick setups, etc., are of MAJOR importance. In my ideal set up, I'd have my 88 key stage piano (Roland FP3), my Hammond XK2 organ, and my 9000pro on the top of the stack. My laptop at the side -- a pair of Mackie 450's with the powered sub they make (100 lbs aaaaagh)and an outboard harmonizer.
This is only a setup for a dream world -- it's totally impractical for most of my work, and takes too long to set up, transport and is too bulky on stage. Today's working musician has to be mobile, compact and versatile, and that's where a kb like the 9kpro really shines. It has just about everything you need in one tidy package, with VERY little compromise in sound. The acoustic piano is awesome, the digital organs are wonderful and the solo wind sounds are amazing.
There are many top end units that offer some of these same advantages, but few have as many bells and useful whistles as the Yamaha.
Feature for feature -- the Yamaha lineup is tough to beat. Of all the high priced offerings this year -- the 9kpro and the SD1 are the only two that have a good kb feel to them. I worry about the psr2k holding up to the rigors of the road. Time will tell, but I have serious doubts about this.
I have been using a psr2k for about a 5 or 6 weeks now, and it really does a great job for what it is. It's reasonably priced, light weight, loaded with features and has a better than average sound system that serves as a great stage monitor, or main system for tiny rooms such as nursing homes or cocktail parties.
I am one player that will never be totally "in love" with any keyboard, but until someone makes the board of my dreams - this 2k is gonna be at my side. The plain truth is - this sucker works. I need that.
