eBay and Craigslist finds

Hi there, I am a cycling newbie and fell into this site thanks to my wheel search. Basically, some scrote decided to steal my Raleigh Misty's wheels (I think they are a 27"). Cut through my locks and everything. Very annoying. But that's London for you. I noticed that this is an Ebay finds area, and assume you must all be bike part collectors. So I must ask you, does anyone know where I can get a pair of 27" alloys for said Misty. Preferably with tyres and cheaper than the £80 I was quoted. I only bought her for £100 and am a poor student who is missing her vital, and beautiful transport. mourns She used to get so many compliments too. If this is in the wrong thread I wholly apologise, if you could point me in the right direction that would be amazing.

I have a 27" track wheelset going for £50 here...
