I have two silver Procyons that are mint. I probably used them no more than a couple of times each. I can see no wear marks. I also have an extra Radius. I bought it used. It does have a few wear marks but not many. I would rate it mint minus. As far as I know, the Procyons have the latest firmware, but the Radius does not. Works great, just not the latest firmware. I have boxes for the Procyons but not the Radius. PM me if you are interested.
