4 years old. It started bogging down on me mid-job. Blah-blah-blah-WEEEEEEE... blah-blah... WEEEEEEEEEEEEEEEEEEE... blah, blahhhhh... sputter. Die. It started back up two or three times with some effort, but then would not start again. For what it's worth, about 2 years ago it started bogging down and I had it "tuned up". I'm headed out today to look for something cheap to use until it can be fixed. Maybe Home Depot will have a refurbished Echo. I stopped at PH Rental and they don't have any used units ready for sale. I looked at new stuff and the Stihl FS 56RC (27.2 cc) may be an option at $219. It's a homeowner trimmer, (replaced the FS 55 R) but I'd rather buyy a Stihl than something from sears - maybe. Depends on what I run across. Maybe I'll find something on clearance somewhere that will get me by.
