RE: power ice auger
It boils down to how much money you want to spend...I've used most of the power augers out there at one time or another and this is how I rank them
1. Nils master - cuts the fastest, is the lightest, but a bit fragile, and the most expensive
2. StrikeMaster Lazer Mag - cuts very fast, not as light, resiliant, cheaper price
3. Jiffy Legend/STX - cuts OK, very heavy, heavily built, strong, will last a lifetime.
4. Eskimo Shark/Mako - cuts OK, heavy, avg build
Me, I own a Nils master.
If I was to go out and buy a new auger right now, I would go with a the strikemaster lazer mag.
Jiffies are the classic, heavy design - will last a lifetime, but the weight wears on your back REALLY quick, esp. when drilling lots of holes like I do.
