I think Aga's are beautiful and from what I've heard those that have them swear by them but they just aren't what I want in a range.
If you really want top end there are other french ranges though:
French Ranges - Lacanche Stoves
La Cornue · Artisan manufacturer of exceptional kitchen ranges
How much do you want to spend?? You can spend upwards of $40K on a range if you like. A Wolf looks positively cheap by comparison.
