I have that saw, and it's a nice saw... plenty of power. Heavier than some of the others, but has been really easy PM, reliable. Have only gone through 3-4 cords with it, but no complaints. Good all-purpose saw, but not one for primarily limbing or climbing with. Best bang for the buck.
Thanks for the replies. Already had an ACE guy print an estimate for me on saw, case, sharpener, etc. But wanted to hear what the experts thought first.
I too have the 455..... been great so far. My only problem was buying a replacement chain. Be aware there are two versions.....the one sold at big box stores have a more idiot friendly chain/bar combo. Ones sold at saw stores have a more agressive chain/different bar. I just bought the more agressive chain/bar combo but have not installed it yet. The 455 has plenty of power, and should take a longer bar/chain in the future if you should need. It is definitely not the saw you want to use for cutting small stuff though... gets heavy after awhile.
I have the 460 rancher as well as a 137 for limbing . Both are good saws. I cut around 20 cords a year . We feed 5 outdoor furnaces here on our place . 4 in home's and one on my shop/office . Not to mention the best guarantee out there 2 years on the saw and lifetime on the ignition .
