Sorry, no trades. Paypal or USPS Money Order. Why pay $599 online? This is "as new" (other than the scraches on top.) Literally less than 30 minutes use since it came out of the box. Never been out of the house. Just didn't realize what the screws in the bottom of the unit above were doing. Don't even ask what I was thinking. The important thing is that this unit has not been abused, but hardly used. $400 shipped to your door...and it will be shipped in it's original box. This shows how little of the scratch shows when the pre is racked.
