I am looking for a portable keyboard that is easy to move and store. I would like to use this keyboard to improve my piano/keyboard skills and eventually record backing tracks to jazz standards using StudioOne and/or Realband. Please see below for the following specs:

61 keys
~20 lbs or less
USB connectable – I recently purchased the PreSonus AudioBox USB96 interface

I would not be looking to spend much more than $500. Generally, this is for home use and not for playing with a band. However, recording capability is key.

Thank you.
