The price is a little baffling-- IIRC it's been a while since convention-exclusive toys have had a real markup from the originals. The listing refers to Nemesis as Voyager-class, so that's less than half of the set's cost-- no way the Star Saber is also a Voyager.
If Nemesis is closer to Leader, that's better. I mean, I don't have Commander Armada Optimus to judge. (I'm assuming the Star Saber would/could be sold as a Deluxe, but that's a total guess.)
Someone please check my initial assertion, too.
Edit/update: I guess I'm saying I want it but am having a hard time justifying the cost.
