461/661 Mfg-listed weights accurate?

[LordFarkwad]

Stihl lists theses as having a 2.2lb difference in weight, between each other. Is this accurate? I've read a few different places that say more like 1.5lbs.

I'm running with a 362cm currently, but want to pick up another saw for the purpose of having one to cut the first one out of a pinch, to be able to run a long bar due to having a few jobs lined up with >40" diameter pines and oaks (less trips around a potentially dead tree, etc.), and also wanted a longer bar for additional reach/distance when taking care of storm damage and blow downs.

I checked at Mid-Atlantic Stihl (distributor) in NC and they said 661's are currently on back-order, and none of the dealerships I've checked at local to me have 661's in stock (nor do they keep them, apparently).

Does anyone have any suggestions as to where I could check on the availability of one of these?
