It seems you are missing my point. I do want the cheapest possible deal with the best possible service (aren't we all)?
In my last message, I am showing that the actual price difference between Artatech and yours is 11 Euros for me. This is 11/349=3% in the best case. For this small difference, warranty and support is (in general) more important.
Hence, my question at the end of my last message:
Am I missing something (in terms of support, features, warranty, etc)?
