Never seen a Dalmer before or saw shop for one. Maybe that's a good thing?
So you will need a bucket of parts maybe?
Even a well known porter aground here took it on as a pet project after the discontinuation of the original 372 but they just didn't catch on in industry. Neither did the 576. Perhaps if they could have shaved some weight on the 576 it would had sold.
The 461? The roughest saw...the smothest saw. Its got the built in power but its got to be raced out properly with the back pressure out of it and the anti-vib handlebars then its way smoother than the AV mounts (372) coming on and off the trigger. However! That's half the battle, its a square chisel saw only. Then I would call it the best saw on the market between Stihl & Husqvarna. Not a big fan of the stock 372 x torq although I've been running the chassis for 21 yrs.
Things on it are cheap now. Chokes, trigger locks and on/off switches.
Those three things mentioned are my biggest expenses that add up fast.
Its the most versatile saw out of the bunch, that I'm sure of. very fast maneuvering saw.
I had bought a new 575 In 2006. I only ran it for a shift. Again, good built in power and very smooth.
For stock saws, out of the 3 saws I would say 576. The 372 has to many cheesy parts for me to recomend and the 461 is rough. Dalmer sounds good but service may be a concern?? If your are not in a hurry then its OK and likely much cheaper on parts as well
