That would be dependant on what type of wood you will be harvesting, and how big. I have everything from a stihl 066, 044, poulans a cheap saw, but I really like the little poulans for harvesting bow woods of medium size. Poulans have definate weaknesses.....one the pull start... don't try to prove your manhood here short pulls, and don't use anything other than the poulan weed eater 2 stroke oil mixes as others will clog the carb... been through this many times!
Get one with a 18 inch bar I prefer the "wild thing" they have more power, kinda ugly, but you won't loose it!
. If you are looking for a pro saw stick with husky, or stihl....my .02.
