Selling Case Catalyst v6.08, don't know how much to ask??

[M.Heeley]

I am an ex-reporter and scopist still holding on to my Case Catalyst software and key, and I realized today that someone out there could possibly use it besides me since I'm not in the field anymore, and they would get a better deal than buying it new.
Only problem is I don't know how much to ask.
If I remember correctly, this was an upgrade for me from version 4.
Does anyone know what the going rate for that version is, or can anyone give me suggestions on what to ask for it?
Also, I don't have support on this anymore, and I don't know if that matters or not.
Once I figure it out I'll post it in the classifieds as well, but if anyone is interested, please let me know.
Thank you.
