If any one gets offended by me posting about aural, I advise you to stop reading now.
Can anyone recommend a good aural training book and CD that I can use to develop my poor skills? Preferably starting at around grade 2 sort of thing...

It needs to be relatively low priced... I'm a broke student at the moment...

I have had a look on ebay, and the only aural book with a CD is grade 4-5, and i is the AB one which someone said is very useful? It is rather reasonably priced at £10 because aparently in the shops they are more than this... But my aural skills arn't this advanced yet... Does anyone know of any beginner books?
