When I bought this property here 10 years ago, one of my neighbours had 5 chain saws and he gave me two of them for free, a 2ci/30cc 16" Poulan and a 2.75ci/45CC 18" Homelite. Me being Dutch, that made me like the guy very much. The Poulan does not have a brake so I know where preferably not to cut, but even cutting with the tip does not require a noticeable extra effort, if the chain is kept sharp.
Although the Homelite was only used twice, he gave it to me because it did cut badly and after a minute or so started smoking as hell. I took it apart and it was immediately obvious: the brake did not release. I checked on the internet and found that Homelite overdid the security; one just had to shorten the spring by one turn and the brake came free. Did that and presto, the thing runs and pulls like hell. The original chain was first class crap too, so I threw that one away and got full chisel for both, brandless from the roll at the local hardware shop, and a new blade for the Poulan because the old one was bent and cut in circles.
I fell four trees each year, hardwood or pine, 20 - 30", whatever stands in the way. The felling and cutting up of the thicker pieces I do with the Homelite, the rest with the Poulan that has a tad more bite. Splitting is done with an axe; takes some time but keeps me fit. Don't ask for my comments while I am actually doing the splitting, though.
As the Poulan does more work, I need a new chain each 2-4 years (abt US$20), dependent on the type of wood; the Homelite lasts longer. It all works perfectly for me this way. I am 75 now, a sad fact which makes me shave nowadays without looking in the mirror.
One last remark re. Amazon: Here the mentality seems to be a lot different. A quick phone call gives me local availability and price, and if the latter is obviously too high, pointing that out practically always remedies it. Availability neither is much of a problem, as long as what you want is somewhere in the country and can be delivered to the shop in one or two days.
