I think its a fair question to be honest...

I wouldn't have had a clue so the question (and in some ways your answer) were beneficial to the uninformed types, like myself.

Foresight is key.. I posted a thread very early this year telling everyone to buy PS Moves for the sub £10 CEX were selling them for, they are now going for £30.00 a piece.

Not an excellent price.
Standard price
But hard to find

You couldn't give these away last year, people labeled them the same as the PS TV ie useless !

any difference from first camera and v2 part from the look?

I bought a few Move controllers from Sainsburys before the PS4 launched for something like £8 each. They had already announced the Move controllers would be compatible with the PS4 so seemed worth the risk back then.

I paid slightly more than this at tesco last week so not a massive deal but still a saving

I think you mean £40 in CEX. They give £28 trade in!

Is this essential for the VR headset?

I paid £45 in Argos this week. Ordered from Amazon and will be returning other one.
