If you have the money and the need for other attachments go ahead and get the KM130. It is only .2 lbs heavier than the KM90 and as much power as you will ever need. Maybe pick up a couple of attachments as well and get a better deal from you dealer. The BR600M is one of the best blowers out there even though it doesn't have the most cfm.
