I have the Echo HC-150. They cut great. It has a 20 inch blade on it but the unit itself is pretty heavy. The only reason I went with Echo was because I paid $279 for them instead of paying $299 for a pair of 18 inch stihl's. Whatever pair you decide to get, make sure you get some 3 in 1 oil and oil the hell out of them after every use. Water is your enemy!!
