I had wanted to replace mine as well with propane, but After much thought and debate, I switched to a hybrid 110V Radiant/Induction cooktop. Of course the advertised physical dimensions were completely wrong so it would never fit in the "well" for the old Gaggenau Halogen.
Then I looked at built in 110V Induction only and didn't find one with the feature set I wanted. Back to 220V with the Induction "flex" surface.. I can use 1, 2 or both at combined wattage to heat large griddles, casseroles, etc. Even though right now i only have one element working!
I preferred the Induction over radiant because of the lack of really hot surfaces after cooking. I switched from propane due to overall safety and losing some space in a bay for the tank. And of course filling and the like.

Thanks for the research Rick, mine has a propane tank already that is only used for the 3 way refrigerator at this time. Don't know if the cooktop was factory or changed by a previous owner.
