I have the M18 Milwaukee Quik Lok system with the weed eater, brush cutter, pole saw and extension, and hedge trimmer (head articulates and can be parallel to ground to demolish saplings and does wonders on emergent overgrow without throwing it all out into the pond like a weed eater). It has been amazing for everything I've used it for. I think i saw they are coming out with a tiller head, but I was impatient and bought Ego's (which I love as well).
