While I cannot say from experience what to buy, I can say DO NOT buy a Poulan. From research that I have done so far, it seems like either a Husqvarna or Stihl is the way to go.
Husqvarna??? You didn't consider Echo? No matter what brand you buy get a carb. adjustment tool (you will probably have to buy it online) and remove the catalytic convertor if it has one (I think the Feds require them on all gas engines now). All 2 cycle engines are set from the factory the to run hot and lean in order to meet Federal emission requirements. Adjust the idle and high speed jets on the carb of you new chainsaw as soon as you start it. Your chainsaw will run better and last a lot longer. Running a 2 cycle engine lean is an incredibly bad idea.
