Reply to What is an Audio 2 + Traktor Pro version 1 upgrade license worth?

I have an Audio 2 as well as the pro upgrade license that I bought before Traktor Pro 2 came out and I was believeing about selling them as I have an audio 10 now. I believe I spent around $180, but I don't believe anyone would even want to buy it as one could get the newer version with the Traktor Pro 2 license for about $70 second hand. Should I sell them separately or just say screw it and keep it as a back up?
