Not all brands make all products well but Stihl handhelds are pretty decent and IMO better than other offerings. They have a commercial grade BG-86 & homeowner BG-56. The build quality is exactly the same, the crankcase/cylinder share the same part no's, but the ignition module is different that gives the BG-86 slightly more speed which is not really noticeable in the real world. The BG-86 is heavier as it has AV springs, it also has a HD-II air filter. I own both models & reccomend you get the bg-56 and save some money, its lighter, built with many of the same parts, comes out of the same Vaginia beach facility and basically makes the same power. Just don't use them with the option able vaccum bag & they will have long service lives. The upgrades on the more expensive bg-86 are not worth the big price increase and make it heavier.
