After using large backpack blowers, the small ones seem incredibly weak and slow to me. I thought my Husqvarna 580 was awesome until I got my Echo 8010. But for a homeowner the smaller ones will do, I guess, lol. I typically recommend either the Echo 580 or the Husqvarna 150/350 which are pretty similar, the 150 being a slightly cheapened Lowes unit.
I bought the Husqvarna 550XP saw (Not the Mark II) with an 18 inch bar a couple of months ago and I love it! It cuts like crazy and the weight and balance of it is so much better than my 1998 55 Rancher. It doesn't wear me out the way the Rancher does. We had a lot of tree damage from Hurricane Isaias - I'm still working on cleaning up our 34 acres - and I wanted a second midsize saw so I could just grab another when one needed fuel or service. My little 14 inch Husqvarna 136 is good for small jobs but just doesn't have what it takes for serious saw work.
I've got a friend who recently retired from the local Husqvarna dealer and I just drop my saws with him when the chain gets dull now. I don't bother sharpening them or even taking them off. He'll give it a quick cleaning and service, sharpen the chain, grind the depth gauges, file the bar if necessary, clean the air filter, check for loose hardware, check the rpms and look the whole thing over for $20 and get it back to me the same day. It's worth it to me.
