Got mine on ebay from Skoda_boy for 500 with the box.
Some are brand new, and some seemed to be sent back refurbished, or simply unwanted by the buyer after short wear.
Just make sure you ask.
Mine is 99.9% new, found some minor scratches but only visible with good sunlight, otherwise very happy with it.
Runs rock solid!
Amazon sells for 550 to 600 too.
