Your existing range is electric. Do you have gas heat already?
Getting a gas range will require an electrician (to remove the 220 from the kitchen) and a mechanical contractor (to run the new gas line from somewhere). That's not cheap.
Even if you buy a $8,000 induction range, it'll be cheaper than a gas range ;)
I love cooking with gas. How can you flambe without gas (yes, a torch, but what's the fun in that)... But I'd never install a gas range into a kitchen without gas there.
Now for convincing the husband, if he didn't get a chance to use it in Rome, a nice tabletop induction element is really cheap. https://www.amazon.com/...tertop/dp/B00GMCAM2G

Getting gas run costs only a couple of hours of labor if your utility runs are not buried behind walls. The cost for pipe, a shutoff valve and a flex pipe is fairly inconsequential.
We did this at our previous house and it was no big deal.
Less is more.
