Thank you for viewing. I purchased this, but since I mainly used the GT6B, I only used this one once and then stored it. As you can see from the images, the main unit is in almost unused condition. There are no scratches, no dullness on the terminals, and no dirt on the back. The box (with some damage) and instruction manual (with some folds) are also included. I believe this is in extremely good condition compared to the ME20B units currently on the used market. Thank you.
