I like the Husqvarna professional saws. I have a 346XP, 357XP and a 372XP, all with modded mufflers. That said, I also have a Husqvarna 345 and it is a nice lightweight with decent power. All my saws get a chisel chain first thing. I know some say they dull more quickly in dirty wood, but I haven't found that to be the case, and I've cut a lot of stumps off at ground level for trails.
I used to have a Homelite Super EZ that was really nice to use. It was old school, but light with lots of power. Didn't like the lack of a chain brake.
