I have one. I think I have 75 transponders for it. I just don't have the time anymore to AI plus I don't use Windows any longer. I have new update on CD which will allow you to install it on Windows XP. I have over $7k invested in it. Will let it go for $4k.
I have been PM'd many times asking if I would sell one ,two or three off at at time. I am not interested in doing that as I need to sell the entire group.
