I have a Stihl FS90R that I've had 4 or 5 years (?) and it's been flawless. They don't show that in their lineup anymore, but they have a FS91R which I assume is the newer version. I've been real happy with it though, and was mentioning that to a friend of mine last year saying how it starts and runs out real nice yada, yada, and his reply was "I'm done with all that gas and oil and pull starting - I bought a Stihl battery unit and it's all I ever need - simple"
