put new blades on the ion and sell the whole auger. Then, start over with a quality setup like milwuakee fuel and a lazer. No need to spend $200 on the kdrill when a lazer is way faster and its half the price or less. I've owned both so yes, I can compare them. Just my opinion. You could probably get $300-$350 out of that ion (as crazy as that is) and then you could get a damn good milwaukee setup. Or, buy the strikemaster if you don't want to mess with drill setup. However, imo the strikemaster weighs as much as my tanaka/lazer gas setup so the weight savings is not there for me on that setup. Many opinions and variables. Thats why i have a drill setup for 10in and less and my trusty tanaka for thicker ice.
