In the UK Alpro is a pretty good yoghurt. I really like their plain one all though it doesn't really have the sourness of a good dairy yoghurt. I made a pretty good soy yoghurt but have not had much luck making nut yoghurts. I added a bit of sweetner as nut milk apparently lacks the sugars to feed the culture. I also read that pectin thickens it but it didn't work at all for me. Have you tried making your own nut yoghurts and if you have what success have you had?
