Yep, jiffy model 30 with the 8" bit will pull you right down the hole!
All you need is new blades on your fin-bore though......about $50.
You have to take extra special care of those blades. The slightest little bump, even hitting a weed in the ice, will wreck them. Cut your holes properly, and put the guard back on the blades. If its really cold and ice is built up around the blades, I'll lean the auger up on something........OUT OF THE WAY.....with the blades in the sun. Usually, that's enough to clear them off. DO NOT attempt to chip the ice off. Not only will you lose a finger, but you can damage the blades, and they won't cut!!
They're touchy, but if you take care of them, you can get a couple seasons out of them.........depending how much you ice fish.
I change mine every season once we have a foot of ice.
