Sometimes it's the little ones that surprise you, I have been very impressed by the little bunnings Ozito chainsaw I picked up, so far it's taken everything I have thrown at it (Mind you, I am always careful to select the right Job for the tool)
I still have to hone out the bore on my Husqvarna, once that's done, it will run a 20" bar, I would have once liked more, but being back in the city now, I don't have the calling.
We plan to move back out to a more rural location when we buy (not as far out this time though) and we will be having a wood heater or two, so perhaps then I will be upgrading myself.
