it seem that every class of tool have one brand or model that really work just right . other try to upstage it with different gimmick , but the obvious best choice keep come through . you see it on jobsite after jobsite . p\/c router , Skil wormdrive , senco finish nailer , Bosch jigsaw ... in the 3x21 sander category there be no better tool . simple , balanced , sturdy and inexpensive for the long-haul . Square shape and small body mean that one-handed operation -lrb- large hand -rrb- be practical , allow for use in way to which other model do not adapt well . this be my second one in -lrb- I do not remember , 15 ? -rrb- year , but a long time anyway . someone decide they need my first one more than I do and help themselves ; it 'll probably last they forever if they be smart enough to keep it . so I get the latest iteration which be just still the best . I think I pay about the same the first time too .
