No one has an AGA? Anyone have any opinions on this brand and/or model?

I'm sorry I can't be of much help. I think you might want to see what your range is called in the UK. Is it an AGA or a Falcon (I think those brands are related and swap badges depending on the market. And then check and see what the folks at Mumsnet have to say about it. Just Google Mumsnet and whatever you find the range is called there- or one close to it. I think 48" may be an American size- not sure though.

Have you considered LaCanche? If Falcons were available here, I would get one of those in a heartbeat.

Here is a link for the Falcon range. See if that is the same thing and then you can post on Mumsnet. Falcon is very highly regarded in the UK. We had a Falcon when I was growing up - it was awesome. http://www.falconappliances.com/products/range-cooking/falcon-1092-deluxe.aspx

Rita, thank you. That does look like the same range. I'll have to look at the UK specs and convert to get the equivalent US size, but all the features/options look the same.

I should have added a link in my original link. This is the range:

MHgirl - how do you like the AGA Elise? Are you happy with the smaller ovens? Any issues?
