Craftsman Edger Attachment

I first bought a Troy Bilt trimmer and MTD edger at Lowes. Took them both back because the TB525 4-stroke didn't have enough power for the edger, but the edger was not designed well either (the rubber skirt drags on the wheel, thus the wheel didn't turn easily, an overall mess to operate). Went to Sears and found their 4-cycle trimmer to be identical to the unit I returned at Lowes, but the edger was visually much better designed and higher quality. In the end, I bought the Craftsman edger (and tiller) attachments, but went back to Lowes for a 2-cycle Troy Bilt trimmer. Since Troy Bilt = MTD = Craftsman, I might as well buy the cheaper and lighter unit (and I got bump feed standard on TroyBilt), but I highly recommend the attachments from Sears - they are differentiated.

I bought this attachment because I thought it would be very easy. It's not for me getting the attachment on and off is very awkward and hard to do. As far as edging it's fair but I have to work very hard at getting a clean edge and sometimes that doesn't work. It doesn't go deep enough or maybe there's something more I should be doing. I made a shoulder strap from an old golf bag and that helped to take some of the weight off my arm it is heavy after while. I'm buying one less combersome. I use the weed wacker all the time and have no problem with that so this will sit now. Anybody want to buy a used one?
