I am not presently a wood burner but have started to put together next year's wood supply. I am building on a mostly forested 40 acres plot so plenty to choose from. I looked out the back windows of my new home yesterday and spotted enough dead and down for next year;s wood supply, right from what I can see from the house. I need a chain saw to start processing wood and was considering using a Husky 460 with a 20 inch bar. When I did some Google searches I kept turning up opinions that the model 555 was a better saw. My real question is not whether either saw will work, I think either one would do the job. The question is whether there is enough difference between the saws to justify the added $150 cost of the 555.
