“I originally purchased the £6 "USB Wifi Adapter for the Raspberry Pi". However this failed (like the original) due to over-heating when left on continuously. This £8 "Official Raspberry Pi WiFi Adapter" has been on continuously for a weather station / web-server for the past two weeks and is quite cool and hasn't failed. So, don't waste your money on the cheaper one, wait until the " Official Raspberry Pi WiFi Adapter" is in stock.”
