How much is that new 460? If you are interested in looking at other brands, the Dolmar 7900 will outcut the 460, weighs less, vibrates less, and in most cases costs less. Dolmar is a quality brand, the only shortcoming being that some areas have few dealers.
BTW, I have a 460 Mag(among many other saws). The next bigger saw will be a 7900.
