weed whacker

Stihl FS131, Stihl FS111, Husqvarna 135R. Looking for relaiability, and value for money, I can go down to the lowest horse power model above, as I do not have heavy cutting to do, just listing what is local. Any pros and cons regarding the models mentioned, appreciate you opinions.

I know I read somewhere someone was looking for Stihl trimmer tanks. The pile awaits your requests. Must be six or more there. They came in a box. I have no clue what models they fit. Might have a pic. Will check soon.
