i use nothing but Husqvarna, all 3 brands are good, and easy to start cold ,but the echo and sthil can be difficult to restart warm,my husky never has been ..i would get a 50CC, anything over that and the weight gets too much with a 20 " bar,anything smaller than 50CC. needs more power and weighs almost the same as a 50CC..Full chisel chain works great only in green wood,dulls quick in hard wood, or dirty wood, i have to cut every thing so i only use semi-chisel chain ,buy in quanity off e-bay or amazon..FYI the husky 350,450,550 ,gets rave reviews online,..
