Hola Buenas Tardes westyorksman, I have found a number of free courses on-line. Some are quite good and others not. Just go to google and type in free Spanish courses. I bought a Michel Thomas course off e-bay which is quite good and cheap. Got to get used to his accent first though but very good teacher. Here are a couple of links that may help for the free ones.

I tried the Rossetta Stone one as my sister has it but didn't like it much. Saying that she likes it so it's down to personal preference really. Adi�
