I gave the 5100 a shot based off reviews and price and they didn't hold up. I'm not brainwashed and am willing to try new and different brands. This is first hand field testing and if you do a search on this model many of them have failed and not just under comercial use, usually the weekend woodcutters are having failure as well. I ran a 7900 and was impressed but no way would I trade the proven performance and reliability of say my 460 for the johny come lately of the saw world. To each his own I just will never own one again.
Must be an Ohio thing ...
