From what I have seen and read, the Husky 4XX series saws Perform and Hold Up Well, for what they are.
The husky 460 is my "Truck Saw" it is locked in the canopy of the pick up 24/7/365. Where we live, trees down in the road are an often enough occurrence, that I picked up the 460 used, for a decent price, for that reason, she ain't Purty, but she runs well, and there ain't No Way that I am keeping "Old Reliable" my 266XP in the truck full time, she IS still real Purty, even at almost 30 years old, kinda like Dancing with your High School Sweetheart, when I pick her up and put 'er to wood.
The 460 has reliable done her service without complaint, and the Wife's 445 (NE), doesn't have a lot of time on it, but it has served well so far, and performed better than I expected of a Home Owner class saw. I have been curious about Husky's 543XP, seems to be Husky's "Forgotten Saw", I never seem to see much mention of it Good or Bad, just "Forgotten". Curiosity got the better of me, and a 543XP w/16" B&C should show up at the house while I am working out of town again. I am wondering if the Wife won't "Adopt" the 543XP as "Her" next saw.
Any how, so far, the plastic clamshell saws have fared very well from my experiences.
