Today I met someone who said, he prefers Dolmar over Stihl sometimes, because they are cheaper for the same quality. But he said, it would depend on the model.
He had every thing from Stihl with Akku in the van and several Dolmar chainsaws.
His opinion was that you get from Dolmar chainsaws for 500 € for which you have to pay 1000 from Stihl. I think he ment the large ones.
He said he prefers the small leave blower from Dolmar and the large one from Stihl.
My brother has a small Stihl for 450€ or 500€ I guess. It is very fast to activate it, without any tools. Especially if you want to cut from time to time something, and not a whole forest in one rush that is very nice.
I like the expensive Stihl patrol too. It doesn't stink so heavily as hand mixed stuff.
For the trousers:
I know someone who buyes only trousers which protect 360 Degrees around the leg after once he cut himself from behind in the leg.
Have a look at tree climbers sites for that.
If it's full of Silky saws and ropes and so on, it should be the right page.
May be, you can find it under the word ARBORIST.
