I have numerous Stihl saws and my favourite was a 20 year old MS260. It was light, powerful for a 50cc, started immediately and could be used for hours on end every day.
Two MS 362 were returned as one was replaced under warranty and the other was erratic. Having a 461, 441 and 462 it seemed Stihl has ironed out their M-Tronic problems (now on version 3), so I picked up a 261 recently. It revs faster than the previous model and holds power no matter how hard the timber one cuts. It has 100s of hours on and I would rate it as one of the best saws Stihl has produced, along with the 460.
Have a look at the US Stihl review site and it has an excellent rating from hundreds of reviews.

Great saw, cuts aussie hardwood like a ninja, chuck norris would use this chainsaw as a beard trimmer or toothbrush... wish i'd purchased this saw years ago...cut 2 years worth of wood in an hour, what a weapon! Highly recommend! Would buy again and so would Chuck...love the captive bar nuts and the the thought stihl has put into this machine....Well done STIHL!

Owned the 261 for less than 4 years and the engine is toast. Told by the dealer that it would cost $400 for parts + $100 for labour. I only use the saw to cut about 3 cords of wood per year, so it is not intense use. I will be looking for a different brand.
