I was also looking at IceGators new 42v Auger called the Annihilator with the 9 1/2 bit.
It is very light weight and can cut 80 holes on a charge, through 3 ft of ice. It can be
left outside in the cold unlike the ION. It cuts holes so fast it is unreal. Downside is it
cost almost 7 bills, and there doesn't seem to be a lot of places to get one.
