Drop just over £150 at Amazon currently and you can nab yourself a shiny new PS Vita, the Action Mega Pack, and an essential 8GB memory card.
The new Vita loses a little visual lustre by swapping out the expensive OLED screen of the original for an LCD, but you won't really notice that unless you put the old and new versions side by side. Put it this way -- things still look great on the new Vita. Crucially, it also comes packing a couple of extra hours of battery life too.
As for the Action Mega Pack, you get five games on that 8GB memory card -- 3 Vita titles (Injustice: Gods Among Us Ultimate Edition, Batman: Arkham Origins Blackgate, and PlayStation Allstars: Battle Royale) and 2 PSP classics (God of War: Chain of Olympus and Killzone: Liberation). You can pick up the Football Manager 2014 Classic bundle for the same price, but that only comes with a 4GB memory card. Believe me, you'll want as much storage space as possible.
