I've been looking at that pizzagroup oven too. It seems ideal, claims to able to hit 430C, yet small enough to fit it a domestic kitchen. My only concern is the fact I only have single phase 230V mains and from the pizzagroup website's datasheet, the oven is 3-phase powered.
The manual from the american importer's site show it just being hooked up to a single phase, neutral and earth on page 13. But the question is whether you can do that on a model sold here in Europe. And yes, the first I did when I read the datasheet was to email the manifacturer, but they can't be bothered to reply apparently.

Oh and uk1, if you're still interested I found a company in Germany on the google that carries the digital line and appears to ship to the rest of the EU
at www . pizzaoven . eu . Click on the 'Pizzaöfen Compact Line m. ActiveStone' link ... only challenge is they appear to only want to sell Companies.
