Dealer support.
If you’ve got a good Dolmar dealer nearby...? Go for it.
However, I’ve given up on being different for the sake of it. Whatever is the go-to saw in your area...go with that one. I like Stihl, Husqvarna, and Jonsered (based on reputation and that they’re evidently built in the same factory as the Huswvarnas). Not to say nothing else is worth buying, but for reliable use, I’d rather just have something that works.
From what I saw in South America,, Stihl reigns supreme. I don’t care how much I like my Husqvarna saws, but I’m not going to stick with something that’s hard to source parts for, and more and more importantly, dealer support for repairs (what with the newer saws getting that fancy computerized doo-dad stuff).
Did you end up with a Dolmar? Liking it this far?
