I was looking forward to have the site available because when I got my 485DI, it didnt have a manual for it. Called Tomball,TX and they said that the manuals arent available anylonger. So, I was happy to hear that this would be coming online..but, when I tried to put in my serial number, it doesnt recognize it. Well, so much for that plan. I am sure it will be a boon to some just as I was hoping it would be for me. Maybe its just too old for them to work with. But I still like the idea..
