do you use as a weedeater?

Just curious on what you guys that have a real choice (assuming you are like me and have at least 10 on hand that aren't completely stripped) on a weedeater actually use in it's intended form...

Personally I have 3 for different purposes:
-Echo SRM 2100 straight shaft 21.2cc, put a Homelite blade on it (free at a garage sale), have $1 for the left handed nut into this one, works GREAT for the tall grass around my creek
-newly acquired Ryobi 4 stroke with interchangable attachments, have a string head and cultivator, got it for $15 because the guy folded the fuel pump diaphragm so the pump had a leak, fixed it in like 15 minutes.
-tiny little 18cc featherlite for small jobs, need to change the shaft though as the bushing is DONE, don't now where I'll find another...

was just curious while I was weedeating for a couple hours...
