Stihl is by far the best money can buy. Its what the pros use and I have weeks behind a Stihl farm boss. As long as you can keep the chain out of the dirt and sharp, they hate wood worse than anything else. It was my boss' and I have used many others. I recently bought my dad a Stihl leaf blower and was talking to guys at hardware store and local small engine shop. Apparently they are discontinuing the ms290 (farm boss) for a new model, believe he said it will be the ms291. Either way it has me thinking of ordering one quick.
Can't go wrong buying used either. Their warranty is awesome but chances are you will not need to use it. They last forever if you take care of them.
