Doesn't have to be a daily user, or even a go to saw... just one that seems to be made for your hands.
With that quote in mind, I say for me its my Poulan Pro 365 or any of the others in that series. The handles and controls are just laid out perfect for me.
I also have a soft spot for the Partner 5000 that was mentioned earlier but like the choke and ign switch on the Poulan Pro 325 better. I also like the way the 262XP feels but that choke lever is just retarded on it.
