I've a copy of Macromedia Studio MX 2004 (educational version) to let go at $200.
It's selling at SIm lim right now at $369.
My copy is original and still in the box.
Let' me briefly explain what's the difference between the academic and the commercial version. In terms of software features, there is none. But under the licensing law, you're not allowed to create work from the academic version to sell. That is why businesses buy the commercial version.
Interested can PM me.
