Deni made one like that, although it is discontinued. One auction on eBay just ended on a Deni Pizza Bella. It seems GREAT considering that there is a stone and top & bottom heat. No ovens to heat up the whole house! I have never used one though, but word on the internet seems positive. Definitely a hard find. The Deni weighs 15 lbs., so even within the States it is about $20-25 for delivery. Overseas would be exceedingly high.
BUT--since you have one already, my only advice would be to NOT cook a frozen pizza on it, lest the stone crack from thermal shock.
