Sell a 420

Hi at all, i don't know if this it's the right section, i sell a 420 already mounted and perfectly working supplied with Usb port. I used it few times. It's like new. Software WIN-PC FULL USB Included.
I sell because i want to pass at the 840 product due that i must do some works more big than the 420 can realize.
I sell at only €.850,00 shipment excluded. I payed €.1.178,00 in kit (The cost of new and mounted is €1.470,00) just because i want to realize soon to proceed to buy the other (840).
I link some pictures of the product.
Thanks,
Giuseppe
