Don't worry, we still fully understand that's a mental price for a controller. But, seeing as the the likes of Zavvi are charging £149.99 (despite the RRP supposedly being £129.99), this represents a tremendous saving. The previous £50 listing was never honored as it was a misprice, so it's unlikely the retailer would make the same mistake twice.
We'd generally advise waiting until a range of hands-on reports appear before throwing down such a large amount of money on a controller. That said, this might be the best price we see if everyone else is charging £150. How about it readers, are mappable buttons and underside shoulder button paddles enough to justify giving this a shot?
