Not your models, but I had an early architect for which KA refunded me the purchase price and I currently have a ge profile. I'm critical by nature, so take that into account when reading the following. GE's grate design isn't the best or even second best. Where the tines open up between burners, small pots can drop through (the continous grates thing is lost on them). You can see the same sort of mistake on the Cafe. Their burner head design is awful. It actually takes LONGER to boil water on the 17k burner than the 12k because the diameter of the burner is so big it can't be used efficently for most pots. Conversely, the simmer burner runs too hot! KA's burners and grates are a better design and deliver more practical heat. However, the refund was because the burners kept melting the porcelain coating off the grates! Both the profile and ka have fairly low power, low efficency broilers. More expensive KA's have better broiling systems. The self-clean works well on both. My profile is two years old. The oven enamel has chipped off in places (naked and rusting are spots the size of quarters) where the racks go. I do not move the racks often. The bottom of the oven has other wierd defects including a 10" circle you can feel. After using both mfgr burners, I think you'd be best off with models that offered dual or triple ring burners. The cafe has at least one and a more powerful broiler. I would hesitate on the cafe because the ones I have seen in person look... well, they have fit and finish issues. Have you checked out the electrolux? It has much the same feature set as the cafe and just under $2k. Here is a link that might be useful: Electrolux

Not a casting issue. The same grates are fine in other positions and other grates that were fine, in other positions wobble if put in the wobble location. Mine has the diagonal wobble on 2 grates. The wobble occurs from the back left of the grate to the font right. This is on the back left and back right positions. Seeing what I read above, this seems to happne at least on two grates for those affected but the positions on the rangetop are not the same. When I go home I will try flipping around the grate supports and see if the position changes. Mine is being hooked up today. I also called capitol for the new trays and supports, since I can see I have the grate spacing/movement issue. I can see the grate hole wouldn't remain centered over the burner without them.

We just built a second home and I spent many hours reading about and looking at all of the more moderately priced gas ranges. I have a 48" Dacor that we've had to 12 years - love it - but bought a Frigidaire gas range for the cottage and it is surprisingly good. The burners are in a couple of different sizes - one small and one for a quick boil - there is an oval burner for a griddle in the middle. The oven heats really fast and no trouble at all baking. The racks don't feel as sturdy as the Dacor, and it seems a little bit less insulated, but all in all for a range under $100 I think it is a winner ! Frigidaire had consistently good reviews on their gas ranges.

I'm just bumping to see if anyone popping in has reviews on the KA rangetop.
