I vote for an Echo in the small saws. I have a cs520 with an 18" bar that use 75% of the time and I burn 10-12 cord a year, only use my 371xp on big diameter stuff. Had the Echo 6 years and not a hiccup one with all the use, just good maintenance. Starts hot or cold, runs longer than I will in a day and real stingy on gas, not to mention the 5 year warranty!!!!!
