Saw update. I replaced the Stihl 210 with a Dolmar 421a few weeks ago. Great little companion for the 6421. No more Stihl, no more flippy caps. Life is good. 421 has 1hp more, just what the doctor ordered, great little limbing saw. I've actually been using it in bigger wood than I had planned due to the light weight and its abilities. If anyone has been considering a 421, you won't be disappointed.
