I got one from Amazon UK for £29.99 before it was sold out there. I then found Argos UK is doing a clearance and sells it for £24.99. Without much thinking I bought my second Belkin.
Thank you for posting this! Quite the bargain. I've just ordered one to collect from my local Argos.
I did buy an Apple Airport Express off eBay, for over £30, which has been OK except it only seems to advertise itself over Airplay for a couple of minutes after it's turned on. After that I can't connect anything to it, and have to turn it off and on again. It's not the end of the world, as I only use it occasionally, and so it's usually turned off. But still frequently annoying.
I did read somewhere that older Apple TVs make for good Airplay receivers, and that because
they're losing support for some DRM video, the price of used ones may start dropping.
