I couldn't pull the trigger on going electric yet. Still too expensive for me. The Echo gas string trimmer I bought however has been working out just fine so far. Definitely thinking that will be the last gas-powered piece of lawn equipment I buy though.
I've got a bunch of echo gas equipment here. It's fairly awesome. Keep Stabil in your ethanol gas and you'll get years out of the carbs. The only battery thing I still have for the lawn is a chainsaw for one-handed stuff, and cutting through the roots down in the dirt (yes I do that). Works great. But man oh man, when it comes time to cut something thick, a gas chainsaw is the only way. Brrrrriipppp!
