The Blade/Libra/San Francisco is a great phone, but it's not available for 50 quid, more like double that (though I bought mine for 70 a while ago, and got an AMOLED screen version too).
Maybe he was talking about the ZTE Racer, a previous best buy in the world of Android. Modaco also have info on getting the best out of that device:
I got my Blade/San Francisco for £75. From time to time there are deals, Argos was selling them on discount, some online retailers were too, Orange had a weekend sale on them a few months ago, and of course the second hand market. But yes you are right, they are closer to £100 than £50.
http://blade.modaco.com/ is a real gem and truly the best place to get all sorts of roms for the phone.
