They've got a load of PS TV's for £15 each at my local ASDA so I picked one up out of curiosity. I found out an exploit allows all Vita software which opens up more games that are fully playable on the TV.
Wireless dual shock controllers seem cheap enough if you go for a clone but there's no cheap alternative to the horrendously priced Vita memory cards. There does seem to be a glimmer of hope on that front.
