Good old Play.com is currently selling the Lexar 8GB class 4 Micro SD card for £5.99. That’s down quite a bit from the RRP of £29.99.
With 8GB, Play reckons you can store up to 1,000 songs, 1,200 photos or 21 hours of video. It’s also “built to last”, but doesn’t make any specific claims about what kind of beating it can handle.
