was talking to my dealer today,while picking up a few chains.\and new av gloves..well got talking and he said he went to sthil seminar thingy,and it seems that the new saws like 441 if i understood him,that these new saws will all have different computer technology,that will have to buy one,machine or cable interface thingy for each model with that technology,which isnt cheap,so i said wont one work,he said no,its a seperate new device for each model saw.......and from what i understand my dealer has to pay for that,that seems tough for small dealers. glad i got ms660 instead.
