It's time to replace my old chain saw ( Stihl farm boss). I was looking at stihls when the guy that runs my local chainsaw shop suggested an echo. The ms 271 is about the level of saw I used to have. The ms 271 price is 459.00. The next size up is the ms 311 at 509.00. The echo cs 590 price 399.00 is comparable to the ms 271. But the saw is comparable to the ms 311. Ms 271 is 50 cc....both the ms 311 and the echo cs 590 are 60 cc chainsaws. So should I stick with Stihl ( prob the ms 271 ). Or should I get the echo?
