Saw the 555 at the local dealer yesterday and was just wondering why this saw never seemed to really catch on.I do not own one or ever ran one,or plan on buying one, but the weight difference in this 59.8 cc saw and my 50 cc 545 seemed very small.He was asking $750 with a 20" b/c. In my opinion this looks like it could be the ultimate saw for a one saw plan.A 562 XP was hanging on the rack right beside it,but there was no price tag and I never asked.
