But our favorite is the Shindaiwa LE260. We are now on our third in less than a year. After the unfortunate demise of the first at the hands of the truck tire

, we bought two more in July. I really like em.
I had 3 or 4 Echo PE2400's. I bought the first in early 92 before they were even popular. It was pretty decent, but suffered from troubles like a lot of 2400 series trimmers do. The first one was great, not because of Echo quality but because of it being the first I bought.
I had one Stihl in between Echos....I preferred the Echo.
I had a Maruyama. It was a good machine. I put it right behind the Shindaiwa.
After buying a Shindaiwa trimmer about three years ago we have replaced most of our equipment with Shindaiwa. I have one Stihl BR400 blower left, but I think I might sell it to buy another EB630.
