Give me to Monday and I will have watched the last two episodes (can't at the mo as I left it at my flat and am at my parents) and will watch the special features.
So far, one of my favourite ones is The Battle Of The Bulge where it focuses on the Medic, for some reason that one just seemed to stand out.
sp00k, the whole set in a lovely metal tin (it's real nice) is £24.99 from a few places online, look here and you can choose which supplier to get it from
