welcome
I wonder if you question would be better stated as "Is a poulan chain saw a good saw for me?
What do you plan to do with it, cut a bit of brush or fire wood once and a while or realy put it to work?
As stated the green saws a throwaway, they might last 50-100 hours, and if you have problems your pretty much SOL. The yellow saws are believed to share components with other more industry standard saws. However if I look in the phone book for dealers or service centers I see shops for Husky, Stihl, Jhonsered, Homelight, and even a guy advertising to servivce john deere, mac and craftsman, but no where do I see where you would take a poulan if you had a problem.
Not much fun shipping it off to the manufacturer for repairs or service.
If you expect to use the saw any amout for more than a couple of years you might want look at investing a few more $$$
