I have an Eskimo and love it. I fish a lot and punch a lot of holes most outtings. I had to rebuild the carb this year, but I've had the auger for 4 years or so... Always starts no matter how cold...I've drilled with jiffy and can't stand them... The blades on the Eskimos last a long time and are cheap when you have to replace them... I drilled with a SM last year and really liked it, but they are so pricey. I got my z51 shark dirt cheap ($220 shipped to my door) from Glens Army Navy in Rapids. I'd go Eskimo or Strikemaster if I was you.
