Not sure why the HF Predator auger doesn't get more love. I've drilled scores of fence post and planter holes with that thing. Use it with ethanol free gas and SuperTech synthetic 2 stroke oil (25-1 during break in with the HF supplied oil, now 40-1 with the Walmart branded oil). After sitting for a couple of months, it typically starts in four or five pulls. Less, if I remember to flip the ignition switch. And nearly always one pull when warmed up. Yes, it will smack you around if it grabs a root or a rock. You learn quickly to hang on tight and ease into the throttle. I sometimes brace it against my thigh in tough holes with a lot of roots.
Very happy to have that thing hanging in my shed.
