Wanting to buy a light weight battery powered weed eater, to replace my Stihl gas weed eater.

There was a thred on these a while back, but I couldn't find it on the "search" thingie.

I'm getting older (67) and the gas one is just getting too hard for me to run.

If a battery model will run for a half hour before needing charged, that would be fine.

It would be break time for me then anyway.

What's a good quality, cheap,(about $100.) lightweight brand of string trimmer to get. ?

Thanks! Virgil B.
