Now if your looking for a nice lightweight 5 cube saw, give the 505 Poulan a go. Mine weighs almost exactly 2 lbs less than my 390xp. Both empty, big dogs, full wrap. And the 505 has the handle a bit more forward and balances much better with longer bars. My 505 weighs around 4 oz more than my 046, so that's about the same as a later 064, but way more umph. That ported 505 runs right with that ported 390 powerwise. I have no doubt that the 390 has a heavier case and larger bearings, but unless you are a full time faller, I doubt you'd ever realize a difference. For that matter that is why the 064 weighs less than the 066.
