I agree with Gary...get a Tyros2.
The E-80, whilst very well made and full of great sounds and styles, doesn't have the equivalent of Yamaha's Super Articulated voices or Mega voices.
Lots of forums supporting the Yamaha as well...PSR Tutorial, for example...a heap of extra styles plus all kinds of tips and tricks.
The E-80 would be my second choice.
Yamaha Tyros4, Yamaha MS-60S Powered Monitors(2), Yamaha CS-01, Yamaha TQ-5, Yamaha PSR-S775.
