Hey fellas: I would like a little input. I have an oppurtunity to purchase a rental 270, 2 years old, chains, case, w/quickstop and fancy chain adj. Saw is about 80% for $300. Seems a little pricey to me??? Other saw is MS280, homeowner saw, about 80%, 4 years old, for $300. I am leaning toward 280 because of power, I beleive a little lighter, and dont really like quickstop feature or fancy chain adj. on other saw. Rental makes me a little leary as well. Input on these would be greatly appreciated! Thankyou!!!! P.S. Should a guy be leary of 280's high-tech carb?????
