thanks ridin'. i'm not gonna be buying one right now. i was just looking at them while i went to buy some edger blades. i figured if i did get one i'd be taking off the duckbill thing anyways. my br600 is only 2 seasons old so it'll be awhile before i buy another blower.
the 570 was $499 on the tag and the 580 didn't have a tag on it so i'm not sure how much it is. who knows? by the time i buy a blower they may already have a 600bts out.
