Morning fellers…
The 550 and 250 are great alternatives. I like them and personally don’t have a bad thing to say about them. Heck the 550 with heated handles is infinitely easier to source than a 261 artic even though
@GCJenks204 could help with that. I’m not a brand war guy and like most any saw… usually
The only reason I didn’t mention anything other than the 261 above is the power to weight ratio given what Ed said about his dad’s physical condition. The assorted other “farm” type saws are really perfect for most homeowner around the house chores, but are typically farther behind the power/weight/durability ratio. Add in a potentially stubborn old guy and the situation could be tricky.
