Weed Wacker Grass Trimmers ?
 

Hi,

It's been about 20 years since I've looked at weed-wackers.
I think that's the correct name; it's the gadget with the rotating
monofilament nylon line spinning at the end of the shaft for trimming grass
by steps, etc. 2 cycle engine located at the top of the shaft.

Will have to get a new one now, it looks like.
Have only 1/2 acre or so; with 30% of that being grass. Still want to stick
with a gas powered one.
Don't really want to spend more than $100, or so.

Would appreciate:

suggestions as to brand, and which to possibly avoid ?

does another $ 20 buy me anything significant?

is the state of the art still that deplorable line-advance system of
bumping on the ground (which never worked
right for me), or is there something better available now ?

Any thoughts would be most appreciated.

Much thanks,
Bob
