Same advice, except don't get a stihl with a number under FS55 (inclusive). They are utter crap in my opinion.

If I were to buy a new trimmer today, I would look at echo or Husqvarna. Bear in mind echo is distributed by briggs, their parts prices are sometimes $$$.

The one I would go for is a 322l Husqvarna, recently discontinued, you will get one for around $550 on run out. The new one is a 522l, exactly the same thing but a different number, will run you $650.

Amazingly light and plenty of power (though only a 22cc motor it really packs a punch). One of the lightest trimmers I have ever used, on par with my old kawasaki.

If I was feeling particularly excessive, I would buy a 525LST for around $850. Bigger motor, 300grams heavier and more powerful. Will last forever in home owner applications. I have seen them beat to hell by contractors and they keep going (aside coils being a bit weak).
