I've bought and worn out several brands of weed eaters. Echo was my favorite gasoline powered one. It started the easiest. I'm not familiar with the model numbers, and it's been years since I owned a gas weed eater. Eventually the Echo fuel primer, then the fuel line got all gummed up from the gasoline I was using, and it sat for too long over the winter that I decided it wasn't worth the money to have the Dealer fix it.
I bought a Makita dual battery cordless weed eater off of Amazon that's been amazing. I put two 18 volt batteries on it and I've never had them die on me before I was done weed eating. It's amazing not having to fuel it up, or wear ear plugs to use it.
