We splurged on a few things in the kitchen, one of them being a cooktop/oven versus a range. The difference is kinda subtle, but the combo allows for a bit more choice over what appliance you want. Also, when it's all finished, it looks a bit more polished to have a built-in oven and countertop cook surface rather than a combo.
We didn't like the gas range we put in our last house, and we were ho-hum on electric. Then we learned about induction. Woah ... cooking with electromagnetic energy?! Are we living in 2010 or what? Oh wait. . .
