Thanks guys,your advise is appreciated. It is going to be used for mostly cutting firewood and downed trees, maybe some trimming. what model and bar size would you recommend?
As others have said; felling, bucking, and trimming are often different size saw tasks. What are you doing most?
A couple weeks ago I took down a dead birch tree in my front yard. Trunk was about 11" DBH and it was already growing shrooms on the upper branches so I rented a bucket lift vs climbing it (I have spikes and all the fun stuff for climbing). Only had a Jonsered 2172 (Husky 372xp) with a 20" bar, which weighs in around 15#. Let me tell you, that was not fun hoisting that saw up out of the bucket to take down the limbs, nor was it fun holding it out over the bucket to section the trunk to where it could be dropped safely at the ground. Really wish I'd had my little Echo cs-352 (it's 10# wet).
Something in a 60cc would be a good choice for a general purpose firewood saw. Plenty powerful enough for felling, but still light enough to not wear you out limbing. My two-saw plan while dropping and bucking bigger oaks is a 71 and 88cc saw, but I'm not normal. :D Once you run a 88cc everything else seems slow.
Today I'm getting my third Echo, which will be a cs-355t arborist saw. It's about the same power/weight as my 352, but in a top handle configuration for canopy work. It also has the same amount of plastic as a Stihl 201T, but it's half the price (literally). My other Echo is a straight shaft brush cutter, SRM-410u. That's been a great tool for me as well, so I have no reservations about the next Echo added to the arsenal. Say what you will about clamshells (Husky and Stihl sell them too!), the Echo's have been good performers for a lot of people for a lot of years. Once you fix what the EPA regs have done to them (gotta remove the carb limiters and tune them properly), they're a good saw and solid value. They don't have the same resale value as a Husky/Stihl, but are you buying it as an investment or are you buying it to cut wood?
Also, don't overlook Dolmar/Makita's either. Very solid performers and light for their power. If Makita (they bought Dolmar in the 90's) had a top handle gas saw for sale in the US right now, I'd have given it a lot of consideration when choosing the Echo. The Husky T540's aren't all that reliable, so I'm going cheap and seeing how it works.
