Just buy a new one.
A bike is like a bed or a TV. You spend so many hours with it, that it's worth whatever you spend on it.
Stay out of the pub for a weekend to save the money and you will love that wheel even more.
The more i look around on the internet the more i'm thinking that alright.
Something like this only it can take a disc.
