I've got the strikemaster 10" with chipper blades and solo engine. Never failed yet, and I haven't done anything special for it in 4 years except run it dry at end of season. It's 28 pounds I think.
It isn't blazing fast, but after screwing around with blades and angles and crap, I can't imagine why people want to do that all over again with a power auger. I haven't sharpened the blades yet, but chippers are easy enough to do if I feel the need.
The Solo has never taken more than 5 pulls, and rarely more than 2 once it has run for a while, and I will drill several holes at once carrying it sideways while running no problem.
your mileage may vary.
Once it has drilled one hole, it only takes one pull to start if I decide to shut it off while moving. I have been very pleased with it from the get go. I carry it in the vehicle upright in a milk crate that it fits perfectly in, never had any smell or spill problems, and never had leaks while on the ice.
