Oh I've seen some A-MA-ZING things if I could afford them, LOL!
I'm trying to decide if I'm going to keep the same configuration in the kitchen, which works well, or tear it all out and start over to get a bigger stove and a proper vent - there is one of those microwave/vent thingies now which functions sort-of as a proper fan/vent. The stove is also a Kenmore, gas cooktop/electric convection oven, and was put in about 2005, verified by the repair guy who came to see why the dishwasher wasn't working - it's the same vintage, Kenmore, somebody had apparently done a DIY on it and neglected to put the o-ring/screws back properly. The fridge is Kenmore side by side installed in 1994 when the house was built, LOL! So I can't say much bad about that vintage anyway. I had one in the house we moved from that was 40", gas cooktop, electric convection oven, and I despised the cooktop, which was some version of black glass and the burner grates just sat on top of that, you had to be VERY careful about scooting heavy pots on those grates because they'd tip over.
Glad to know that the center burner is fairly useless - thanks for your review! I'll stop lusting after that now unless I put in a larger stove and it has room enough - I'll know what to look for!
