Anything more than $250/£150 will be too much (i'd consider that the limit). While that's still an awful lot of money for a peripheral, i doubt VR has much of a chance at quick success with the casual/general market anyway. It does, however, have a lot of potential with the core market, who tend to be willing to fork out a considerable amount more money on this kind of stuff (such as spending $400/$500 on a console that's only just come out).
Offer those such people an exiting new way to experience a game for that kind of price and a lot of them will happily jump on the offer. This is all unassuming the product itself merits the cost of course (AKA ain't shit).
