Do you think the price is a little high? If you want it cheeper (avoiding Amazons royalties), feel free to email me at email@example.com and we can arrange a paypal transaction (of course this comes without the amazon guarantee).
I think it's a bit high because it isn't MMF 1.5, which is the proper version at the moment. Version 1.0 is truly obsolete now. Still better than any version of TGF though. I doubt any potential buyers will know about the current version thing though.
Anyway, good luck with the selling and the C++ programming.
