Cheapest way from Traktor LE > Scratch Duo 2?

Cheapest way from Traktor LE > Scratch Duo 2?

I currently own Traktor LE, that came with my Kontrol X1. Could someone tell me the cheapest route to take to get to Traktor Scratch Duo 2? I already own the control vinyl and an audio8dj as well.

The upgrade pricing on the site is too complicated and makes my head hurt.

I don’t see a break in price to go to Scratch Duo2 if you already own the Audio 8 so it looks like $339 US to get Scratch Pro2 upgrade.
