I was using this until very recently, and there have been no particular malfunctions or problems. I've used it for several years, so there are some minor scratches on the main unit, but it functions perfectly and can still be used. All the original manuals and documentation are included. I want to sell it quickly, so I'm open to price negotiations if they're not excessive. Please feel free to suggest your desired price. Thank you.
