Are you looking to build the kits or collect them?
If you are going to build them,  you are better off financialy to buy one of the base kits from Tamiya or Dragon and the get some aftermarket goodies to do the version you are after. While the Cyber kits are cool, they are a bit overrated and overpriced. 
Don't get me wrong, if you want to build that particular version, it's nice having it all in one box.  But if you're after it to collect and missed out on the first go around, them you better be ready to fork over some coin.
Just my opinion though.
Good luck, Ed
