MY new blower is a Columbia which is apparently the Canadian name for troy built which is basically a premium MTD
my neighbor has an older MTD from Menards 8hp 24 inch
My dad had an Ariens , and now has a Johndeere which I also think is a rebranded premium MTD
as PRN mentioned
most are MTD , decide what you want for features , 8hp 24 inch two stage is about the smallest I would go , they don't do HP any more but CC most are 243cc that I have seen
My new blower is 277cc 26 inch cut with a higher auger shroud also to cut deeper snow
I sometimes wonder if I should have just repowered my old blower with a Predator motor from Harbor freight but it was a heavy old beast from 1975 and the new one is very nice to run
mostof the time if you take care of them put good fuel in them and use a fuel stabilizer all the time will go 20-25 years easy enough
put some penetratingly oil on any of the cables , and connections , a coupel times a year , use a good fuel stabilizer. I use Startron
change the oil come spring , hose it off to get rid of the salt , oil your cables and pivot points and such and store , start it up about thanksgiving and run it even if it doesn't snow much start it up and run it for 15 minutes a month through he snow season and you should get many years.
my dads areins he bough in 1985 about 2005 he had surgery and mom had to run it , she had difficulty starting it so he bought a new one easier to start for her I ran hos old one another 5 years before breaking a part and finding another blower for less than the part cost.
