Are these saws any good? I see you can still find them here and there around the nation NIB
How do they stack up against Stihl's
I've got two CS56s and love them. In my opinon, Stihl does not make a saw near as good in this size-range. I wish I'd bought more when I had the chance. When Deere stopped selling them, I found a dealer selling them off for $290 each with 20" bars. I'd bought half-a-dozen had I known what nice saws these are.
If you compare the Deere/Efco CS56 to the Sthil MS290 the Sthil loses easily. CS56 has a metal bar cover, compression release, twice the warranty, better power-to-weight ratio, decompression valve, primer bulb for cold starting, etc.
Stihl has made some great and some bad saws over the years, just like many of the most popular companies. There was a time when Stihl sold some of the best saws in the USA. Not anymore. Efco and Dolmar are every bit as good, and often better with a lower price and longer warranty. They aren't new companies either. In fact, Dolmar is older then Stihl (but not by much).
I've had problems getting parts for some Sthil's once they were 20 years old - so I assume that any saw can be a problem for parts when time passes. I'm talking expensive pro-saws, not little homeowner toys. Especially my 045 Super and 056 Magnum.
I worked for one of the first Sthil dealers in the USA back in the 60s, and have been using them ever since (along with other makes).
