True but people do. Where are you getting that a 261 sells for 600.00? Tell me Darling is this 12 or 6, seems you don't know the differance anyway,LOLOLOL
Here you are looking at $579 for a 261 with a 20" bar. Maybe you could get that down to around $530 or so. I may have to pick one up sometime, after the budget recovers from the last CAD purchase.
346's (most new ones I see now don't have cat mufflers) can be had for around $460; the 5105's come in at around $480 - but those have the cats that probably have to be ditched. The 5100's are long gone. So, street prices considered, the 261 is still a good $50-70 more than the competition.
I can't speak to the 261, but they sure look like runners from what I've seen here. They feel nice in the shop, and seem pretty close the the 346NE and 5100 size wise. I have the 5100, 346 OE, and NE, all stock and no cats. From these 3, the 5100 seems a bit stronger than the others, and will happily run a 20" 3/8 all day. The OE is my favorite limber, is light, and cuts like a laser with a 16" .325 bar. The OE has noticeably less torque than the NE, which seems to have less grunt than the 5100.
All are great saws. Even and "old" 260 is a good peformer. Put a few extra holes in the muffler, and let it breathe. With a 16" 3/8 bar it ran like a champ. I sold an older 260 that had seen a lot of hours, and it was probably my most reliable saw.
And going out on a limb, by a small margin, the Stihl's seem to have the best quality of the bunch. I run Dolmars and Huskies too, but Stihl just looks to have a slight edge in build quality.
Regarding the OP, if I were buying new today I would look at the 346NE and MS261, and see which one feels best. The 346OE and 5100 are gone. With Dolmar, I am having an increasingly difficult time finding a real dealer. It used to be worth the hunt as the 7900 and 5100 are such great performers and were excellent buys. Now that the prices have gone up considerably, not so much.
