After messing around with gas-powered string trimmers and not liking them, I'm looking into cordless electrics. The CORE gasless trimmer seems to be a decent machine from the reviews. There is also a local dealer to get warranty work. It is a bit spendy at $300+tax, although I can console myself that it's US-made.

Thoughts or other cordless string trimmers that have been good to folks?
