Well almost 74 and have ran a lot of different saw.
Since 2015 I've bought 4 Echo Chainsaws. Semi retired and don't run a saw everyday. I'm not in a hurry. I'm not logging. I cut a few residential trees that threaten property and cut a few cords of Firewood. Of the Echos I've bought only 1 saw I didn't like. ALL start easy. Run decent and after 6 weeks Being shelved with gas in them ( yes I'm getting old and lazy) they still Always crank. I don't recommend the cs310. Frankly it's not a value at 200 bucks when the cs352 is so much better. Don't be fooled by appearance. Compare the AV, air filters and yes 4 cc bigger engine makes a huge difference in small engines. Back in the day Poulan made a nice 60 cc saw the 380 Poulan Pro. It had AV and was a decent saw. The Poulan 2150 no AV gave me numb hands but mine was decent. At this time I'd never spend money on a cheap saw that could be applied toward a good echo. The cs590 is a decent saw and handles a 28 inch bar for that big tree every once in a while. Most times It's wearing a 20 inch bar decent chain. The saw that sees the most use is the cs352. My first one had a flaw. Not a big deal. Nothing the dealer could not have fixed for just a few bucks BUT HE DIDN'T. Any person clearing brush will eventually drop a chain. My cs352 wasn't a month old and a saw Brier flipped the chain off snapping the plastic Chain catcher. It broke off of the clutch cover and I took the saw back all happy to be quoted a price for repair instead of warranty. So that ruined my buyers joy. I repaired it myself and that's been a couple years ago and no problems since. Unless someone is using a saw to make a living working day in and day out my Feelings are Echo probably is a better deal than buying big Name brand saws. I still own some Sthil saws but never use them with the exception of my 029 Farm boss with 18 inch bar. I use it because I've got it and it does a good job. Tried to sell it for 300 to my nieghbor. He had a big pine blow down. He was amazed how well that saw cuts. However it's not stock. Changed the spur to rim drive. Very good bar and chain plus muffler mod. A very good Chainsaw. Well built. Not an every day all day saw but danged well worth 300 bucks to me. It's 54cc (I'm thinking) and the cs490 Echo is 50. There's no comparison. The Sthil smokes the Echo 50 cc saw. But price wise the Echo is a lot cheaper. Just my opinion. Feel free to voice yours.
