I've been running echo trimmers for alittle while now. I actually like the 210 model, light and easy to use. if it ever breaks in 2 or 3 years, $200 for a new one. Bu tthe one thing i hated about the echo trimmers is the head design. I love and missed my Redmax with that stye head. it would last so much longer and was easy to load, and replace little pieces that wore out. this week, my echo wore out as usaul, every month and a half, so i bought the red max head and put it on. the thing is, its the 4" head, holds more string, and i really like it ($50 ), but do you think a bigger head is just asking for this model of echo to break, or does it not matter? this is a pic of the head i bought today for reference.
