I'm hoping some of you guys might cut and sell firewood during the off season. The MS 270 has all the bells and whistles of newer model chain saws (quick chain adjustment, advanced anti-vibration, etc) but only has 3.4 hp compared with the MS 310 that has 4.0 hp but no bells and whistles. The MS 310 only cost $10 more than the 270. I'm leaning toward the 310 because of the horse powere but would really like to have the features on the 270. The models with more hp with the features are out of my price range. Question: Will the horse power of the 310 make much difference? Or, will the features of the 270 be worth it over having more horse power?
