looking for a used Heat Watch system

We are looking for a used Heat Watch system. Anyone know where one is for sale?

Thank you

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.

We are still interested in finding a used Heat Watch system. If anyone knows of one for sale please let us know.

Thank you
