I beg to differ with Fran.

I use the PSR2000 on the job every day, usually twice a day.

The PSR2000 isn't the sturdiest keyboard in the world. I own two. It has never gone completely AWOL on the job. I blew the internal amp once and had to rely on external speakers. I blew a speaker on the other one and had to rely on external speakers then too. Several times, I've had Style Control buttons start to go out, requiring harder and harder pressing. Once I had this repaired at a service center, but it took too long. The other two times, I had a tech geek friend fix it. He replaced all of the connections on all of the Style Control Buttons. So I've had these problems. But this is after using the keyboard for hours every day, week after week.

The PSR2100 will probably come with more onboard styles, improved harmonizer, slightly improved speakers, much more voice rom - so you'll get all of the Tyros voices except for the Megavoices. You get the USB - big deal. You get twice as much flash memory - a measley 2mb instead of 1mb. I think that's it. I don't think the PSR2100 will be such a step ahead of the PSR2000 that the PSR2000 was from the PSR740. But for me, these improvements are significant, and since I make my living performing, it's going to be worth it for me to purchase it. In fact, I'm going to buy two PSR2100s and get rid of my two PSR2000s.

Unless you have a lot of money, or unless you really need those megavoices and flash memory, I would go with the PSR2100. But to have fun in the meantime, maybe I would buy a used PSR2000. Sell it in July or August and get the PSR2100. The biggest improvement you'll experience with the PSR2000 over your PSR740 is that you'll be able to load styles lightning quick from the floppy drive. On the PSR740, it takes almost 10 seconds to load a new style. On the PSR2000 it takes 3 seconds.

Good luck,
