I can only speak about the Hayauchi pole saw and the one that home Depot sells for around $100 Cdn. The Home Depot one worked fine for the first two years till I bought the Hayauchi...it was like night & day. The Hayauchi's blades sell for about $49 US but you can swap them with the Ibuki hand saw blade in a pinch, (its true). I also like the locking system of the Hayauchi over the ARS, the ARS has a Chanel on the back that begs to be filled with saw dust and other stuff. regarding the plastic locking tabs on this pole saw...i rarely use them. I prefer to use the metal button to lock the sections in place. For a the bigger company, a more durable pole & saw would last longer and hold up better over the aluminum ones. If this saw is just for you or a small crew that takes care of the equipment, the I would go for the Hayauchi 21' Pol saw. My .02 HC
