actually, redmax makes the shindaiwa eb630, and eb630 rt. it is just a rebaged redmax ebz7001.

shindaiwa makes all their other blowers though.

redmax makes all their own blowers, they are the american branch of zenoa komatsu. if you have a choice though, go with good dealer support. there is almost no differance between the ebz7001 and the eb630, although, the redmax has a sleightly better air filtration system.
