"Big Red Baby!!!"

Feature:
Does what I need for live playing! I use most of the features. The light weight is one of my favorite features... and if somebody interrupts your power, it reboots into exactly the same state.

Quality:
Built for the road, no worries.

Value:
It's pricey... but it's the best for what it tries to do.

Desirability:
It's red! It sets up in 2 minutes. It weighs under 40 lbs. It rocks. Maybe not a great investment if you already have a bunch of keyboards... but wonderful if you want to cover all the basics in style.

Sound:
Sounds are great out of box, but really reward a bit of tweaking. The keyboard is well-connected to the sounds... very expressive instrument. Could have a few more sounds, but the sounds it has are perfect. Latest OS (2.0) adds two completely amazing piano sounds. For extra marks, amplify the Stage in stereo... but it sounds good in mono, too.

Ease of Use:
No real need for a manual once you understand the organization. Preset voices give a good sampling of abilities. Latest OS upgrade improves on a great start... more upgrades to come (easy to upgrade).

Support:
Not sure... haven't had any problems.

Overall:
If you can afford it, and you really want an instrument with depth (not just a keyboard) this is the one. If this one were stolen, I would buy another one tomorrow (ouch).
