I need to purchase a new blower for the winter. I'm looking at the Ariens 1336,1332 & the Troy-Bilt 1332. The Troy is 1800. the Ariens are 2229.& 2429. respectively. I have a large area to do including gravel driveways. Any advice you can give me will be much appreciated. Since they all use the same engine I guess it comes down to durability and ease of use as the deciding factors more than price as I intend to keep this unit for the long haul. Thanks for the help.
