I have never used this model, but after 7+ years working for the Big B I have a lower opinion of Spear and Jackson. I have had their shovels break, their knives and screwdrivers and allen keys bend, but that might be my fault.
I might serve you well, but not work well enough for the next bloke, or vice versa. At the end of the day, it depends on your expectations and use of the tool. (I am pretty hard on tools).
I broke 2 of the Ozito electric staple guns on canvas and pine frames, then I bought a Ryobi, no problem so far.
