We are building for the second time and we are going with double Electrolux ovens this time. A friend who cooks cakes professionally just put them in her kitchen and raves about them so I'm thrilled. I can't remember the size off the top of my head (600 or 700) but they're two full sized wall ovens with one set of controls above the top oven.

We had a 900mm Westinghouse in the last place we built and I don't think I'd go 900 again. There is actually a lot of wasted spaces, even if your oven is 'full' as the oven trays aren't the same size (length) as the racks and there is spare rack space which can't easily be filled (unless you've got skinny trays or dishes that fill the gap perfectly, I didn't). They're a lot of oven to heat up if you're only cooking something small too. Hence why I opted for twin ovens this time. We had issues with the seal on our 900mm Westinghouse too which turned me off that brand. Although I think Electrolux and Westinghouse are actually made by the same company!

I joined Choice Online to get the dirt on all the household goods. It's been a good little (cheap) investment. I did the same when we built our last place. You can purchase the individual reviews too if you don't want to sign up for all the reports.
