ok so the price difference does not make it worth it.

I know this is not the right forum but what's your opinion on the Yamaha P80 and Kurzweil sp88 ?

I'm hesitating between the 3
Technics sxp 50
Yamaha P80
Kuzweil sp series

The cheaper is the Kurzweil sp76 semi weighted.

Is there a big difference between the semi-weighted keyboards and the full weighted ones? I mean semi is still acceptable right?
