If you're looking for a shooter to play on the go, this is probably the best experience you'll get on the Vita. Amazon have price matched the current cheapest deal at ShopTo, meaning there is a choice of where you want to get your £3 saving from.
The port to the Vita isn't flawless, but it's a faithful one that brings the entire Borderlands 2 experience to a handheld. With most of the DLC included in the purchase, and the ability to cross save with the PS3 version, fans of the series might see it as a reason to return to Pandora. Thanks to pauledwardking1 @ HUKD!
