I have replace a 20 year old Craftsman belt sander with the 9903 Makita . I always fight with the Craftsman 's tracking . I could only go 5 minute before I need to adjust the tracking . the Makita be not like this at all . it have perfect tracking ! I pull the 9903 out of the box and it track ok with the stock belt . but when I put a 3M belt on it and tweek the track a bit I have not touch the tracking , even when I change the belt to a different grit . I highly recomment this belt sander and 3M -lrb- purple -rrb- sand belt . you can turn 9903 over and clamp it to the bench , great feature . it have a very nice trigger lock button , easy to set when you want to set it - but not so easy to lock when you do not want it lock -lrb- with either hand -rrb- . a add benefit be that this belt sander be that it be very quiet -lrb- as belt sander go -rrb- . my only complaint be with the availability of accessory . I can not find a sand frame or a vacuum attachment . when I go to a authorized dealer for Makita and ask for a quote on a sand frame they quote the housing of the 9903 . buy this one , you will not be disapoint .
