Hey lawnsiters. Yesterday I bought an Echo SRM-210 trimmer, and I thought I would share my opinion for anyone that might care. I purchased it from Home Depot for $219. The 21.2cc engine seemed incredibly small and I made sure that I could return the unit if it wasn't what I wanted. The entire unit is very very light, and the cushioned handles are awesome for comfort and anti-vibration. I tested it out on a patch of 8 inch grass, and a very thick 6-8 inch patch of clover that my neighbors were kind enough to lend to me ;-) Oh and it had just stopped raining also. The trimmer started up on the third pull, and I let it warm up for about 5 minutes since it had never been started before. Then I went to work, and it was just awesome. It cut through extremely evenly and quickly. I could easily cut everything down to bare earth w/out even trying if I wanted to. (which I did want to in one spot just to see if I could) The trimming along a fence row, and around trees was effortless. The Echo websites one liner for the unit says "Straight shaft trimmer is perfect for medium-duty commercial applications." And that is exactly right. I suppose if you were trying to cut down 2 foot tall weeds, and lots of them you might need more trimmer, but I, along w/probably 90% of us, do not do that regularly, if ever. I am a very small operator, w/20 weekly accounts, and I am very confident in this trimmer to do more than what I need. Hope this helps someone out there! Now bring on the "you need at least 25cc's or more to cut a weed" comments.
