About 10 years ago I set out to find a good firewood saw, and narrowed my list down to a Husky 353 and a Stihl 250 based on some online reading, and following the Chainsaw threads here. I had further settled on the Husky and stopped by the nearest chainsaw shop for a final confirmation. The local guy had either, but at the time was a Dolmar dealer and told me for the money, the Dolmar PS 510 was an excellent saw, at a great price. I bought it and sawed a metric crap-ton of oak, mostly standing dead Red with it.
As I started getting into larger trees, I found an amazing deal on a PS 6100 as the last saw in inventory of a different saw shop that was going out of business. I hesitated, then double rationalized and went back the next day. The dealer still had the saw, and as he was going out of business, he gave me his sign, and a hat too.
A couple years later, I was involved in a large trimming project at our church, and a crazy local Tree man loaned us a bucket truck for a Saturday, and I was the only one of a couple of us who was willing to do the trimming. I had always wanted a lighter/smaller saw for limbing once the big oaks were on the ground, and with this opportunity to work from a bucket, I decided to add the 421 to my little arsenal. It is a great package for my needs (ok, it was for my wants). I love it and often grab it when a bigger saw might be better.
Hence the family. My local chainsaw shop is no longer a Dolmar dealer, but does deal Makita. Truth be told, he has kind of moved on to his custom saw milling. But, he has had no problem getting me the few Dolmar parts I've needed in the past couple years, whether from old stock, or from his Makita network. I am of an age when I might not ever need another saw, and I would be sorry I couldn't likely find a Dolmar in red if I did.
Not sure what you are looking for an owner to tell you. My three saws work all winter long here on my little one-man, one dog firewood operation. I've never had any of the three leave me out of service. I never did buy, nor run either a Husky nor Stihl, so I am not able to declare the Dolmar is as good, or better than either. They are clean and strong design, they work, and they look pretty on my shelf. All I was looking for.
