Best ice auger SHAFT for use with a cordless drill?

[fishnate]

I've owned a SM Lazer for many years and had zero complaints. I tried out a K-Drill the other day powered by a Milwaukie and I wasn't overly impressed. A friend has the new SM Lite Flite and it's similar to mine in performance. In my opinion, I'd say the drill is probably more important than the bit when comparing Strikemaster, Nils, K-Drill, etc. Get a good 20v.

What kind of drill motor do you use Nate?

Sorry I didn't see this, but currently use a Porter Cable 20v that's been pretty good. Not long enough battery life though. I've also used Dewalt with good results. Can't afford those high end drills.
