( I hope here is good place for talking about it.... if not - big SORRY )

I want to buy keyboard for about 500 $.

I want "full panel keyboard" 88 keys.
With MIDI option

Other things like scrolls/modes/sounds/ aren't important for me. I have all of this "tools" in my PC STUDIO

So... I was looking for the best keyboard for me for two days. And the best - I think - piano I found is that model
M-AUDIO - ProKeys Sono 88 - 88-Key Portable Digital Piano with USB Audio Interface

and just like I said i THINK it's good.... but I prefer to be sure :D before I will buy it. Maybe You know something more about this model or better one in similar price. I'll be greatfull for every advice.
