Please, give me your sincere opinion about that: to have a korg Pa50 as a second keyboard next to.....the korg Pa80.
Pros: good sounding unit and extensive editing capabilities in progam mode, can be used as a backup, I know the os perfectly since I use the Pa80, 256 styles locations where I can put on converted styles.

Cons: to not have the joy to discover something new

My other possible choices: yamaha psr3000 (but to expensive for me, now), exr5 (but not so good comments), casio wk3700 (but I want a 61 keys kb), triton Le 61 (but it is not an arranger)

Thank you for your opinions
