Which chainsaw size for cutting a large spruce into firewood

[Malco]

Hi,
I have a chainsaw dilemma. I recently had a 90 year old spruce felled. Most of the branches have been cut into lengths no longer than 12 inches diameter. However the trunk, which is 20-30 feet long varies in diameter from 2ft 6" to 5ft 6" . As I am a beginner ( although verbally coached by the tree-feller at the time), I will not be able to buy a chainsaw capable of ringing the trunk, so I anticipate slowly cutting chips/slices off it which I can chop/saw to fit in my wood-burner. However, I suspect I will need a hefty saw (? around 50cc) to complete that task, despite requiring a much lesser powered saw to cut up the branches. I am unlikely to use the chainsaw after this large task. In the interests of safety, I will go with a Husqvarna but I would welcome advice on which is the cheapest of their range which will be able to carry out the full task.
I am thinking, perhaps the 440, 445, or 450?
My dilemma clearly is that I do not want to overspend on something which has a time limited value to me, but neither do I wish to waste money buying something that is not up to the task. I should add that tree is on a very small island so normal logistics do not apply!
Advice please!

Save your money and your back. Hire a decent Arborist to come in for the day and log it up for you. It will be cheaper and more importantly safer.

5ft diameter spruce will be awful to process to firewood with a small saw. The heartwood will be bone dry and won't rip (ie cutting with the grain) cut well at all. Best to hire in an arborist with a 120cc saw to ring it up and split it for you. You'll save money and your back.
