Love my 2 stroke strikemaster 3hp for burning a pile of holes in short order no matter how thick the ice. It's been running great for 25 yrs. As the kids are getting older and off to college, I likely won't need to drill so many holes. And, as I get older, I have less of a tendency to want to have a workout. If I start wanting to hide out in a fish house all day or only pop a few holes here and there, I can say I would rather have an electric (no fumes, no noise, no spilled gas) and the K-drill idea has me intrigued. Got to drill a hole with KDM's Ion last year and thought it did a great job. I don't know anyone with a propane.
