Solomon82,

My 2 cents worth. I own both a Roland EXR7S and a Yamaha psr3000.


1. I personally like the styles on the Roland better. If you can possibly afford the difference in price, and decide on the Roland, try to go for the EXR7S. It has 4mb of flash as opposed to 2mb on the EXR5. If you like the availability of styles however, you can't beat the Yamaha for that. Although there are definitely plenty of styles around for the Roland, it is nothing compare to the thousands of styles around for the Yamaha.

2. If piano sound is important, again, try to go for the EXR7S because it uses 2 of the best pianos from the Fantom x. These are not present on the EXR5.

Again, if you can afford the difference in price, I would compare the EXR7S to the Yamaha PSR1500. In the voices department, I think the Yamaha psr1500 has it over the Roland EXR7S with the exception of the piano.
