I stopped by the local tractor store last night for the first time in probably a year. And noticed they are now selling a 460. The sales guy said that the 455 is the "junk the box stores sell". Not that I'm looking for a saw but I like to keep up. Whats the deal with the 460? To me it seems heavy far heavier than my 55 Rancher. I guess I'm glad I got one of the last new 55s.
