I looked at several models before I purchased my PSR2000 (from George!). I had played the PSR 550 and then the 740. That was the highest the local music store had. Then I went to another store and they were selling teh MZ2000. I was not impressed with it compared to the features I knew that were on the PSR2000. When I finally made my decision, based on the trials on the keyboards I could find and a LOT of research on the web, I went with the PSR2000 untested.
I have not been dissapointed with it. I performs as advertized and is a remarkable keyboard for the money. The MZ2000 was the same price in my area. It did not have the vocal harmonizer (an option that is getting very popular with my kids for karaoke) as well as other options that I use.
I would not hesitate to recommend the PSR2000 depending on your needs. I am pleased with the support that I got through George Kaye as well. The people on this forum know their stuff and I would recommend going through the archive to see if previous discussions help you make your decision easier.
Good luck,
