I bought this about 1 1/2 years ago and just don't use it that much. It's fully functional and I have the original box, and power adapter. They sell new on Musician's Friend for $279. I'll cut mine loose for $140 shipped CONUS. Paypal only. Here's a good demo showing what it will do: http://www.tc-helicon.com/harmony-g-xt-in-performance-with-tom-lang/ As you can see it has the software bundle, AC adapter, USB cord and manual. It works and sounds great. Only reason I'm selling it is to fund the purchase of a wireless mic.
