Recommended keyboard/synth?

[Master_Z]

I'm looking for a sub-$600 keyboard that will be good for inputting notes on the computer, as well as serve as a good practice keyboard. I do not want a Casio or Yamaha. The Roland Juno Di seems to be a great option, but I'd like to see what else is out there. Thanks.

Dunno why you don't want Casio or Yamaha, but ok.

The other one I recommended previously based on reviews and price was the Korg SP170: http://www.amazon.com/Korg-SP170-Digital-Piano-Black/dp/B002VO0F1W/ref=sr_1_1?ie=UTF8&qid=1312911489&sr=8-1

Casio keys are generally way too heavy and the sound is subpar. I assumed Yamaha is similar since it's a budget brand. The Korg SP170 doesn't have USB.

Any more suggestions, guys? Realistic sounds + 88 keys + USB is what I need. I have  Casio Privia PX-200 right now, but the keys are way too heavy.
