I'll know a little better where I stand after tomorrow or Sunday at the latest. By then I'll have had a chance to run the 590 and see how it compares to my box store special. I think it was Doug who brought up an interesting point, one that I was going to mention: Probably few of you have much if any experience on one of the basic homeowner models. Or if you used one, it was a distant and unpleasant memory. So it may in fact be hard to compare the pro models you use to the box store specials. For my saw, it doesn't owe me a danged thing. I saw the owner tossing it in the general trash at the landfill and I said I'd take it off his hands. For one thing, it didn't belong in with the general refuse, as it has metal that can be recycled. For another, I liked the idea of getting a free saw and it looked like it had hardly been used. That's why I called it a "dumpster special." It was going in the trash. After replacing the dried and broken fuel lines it has never failed to start and cut anything I have. Granted, nothing was over 20" or so, but with a sharp chain this saw did all I asked of it. I am looking at some of the bigger standing ash I'll be taking down--ones with 24" or bigger trunks and standing tall. A tree expert would probably top them before putting them on the ground but I have the luxury of dropping the whole tree so long as it doesn't kill me first. I'm having second thoughts about my little green saw with its 18" B&C. I'd feel more confident with something bigger and with a bit more power. Maybe just a psychological edge, I don't know. Like I said, my little Poulan doesn't owe me anything--if it quit tomorrow I'd still be ahead. I've been using it for over five years now. I appreciate the replies--I'll check in with what I decide to do.
I prefer to be able to cut from one side of a log, sometimes it’s just for convenience and quicker, other times there are safety or accessibility issues that demand cutting from just one side of the log
Something else, having a more powerful saw, can be a safety issue in some circumstances, like a leaner, or tree with rot, you may want that back cut happening a bit quicker to avoid a barberchair. Sometimes a plunge cut will be the answer, but having the ABILITY to make the back cut faster, is Rarely a Bad thing
