I've been using the EuropaSIM for a few months now in Germany and Belgium - works well.
It's essentially a re-packaged Voda IT SIM, but the German guy supports online top-ups with an 3.90-ish fee per transaction.
Good service. I don't speak Italian but need mobile email - slot the SIM into Novatel MiFi and it just works and powers my smartphone plus tablet in hotel rooms plus out and about.
