yes you can make a good om yourself.problem is you need a mill and lathe.i made one and am gonna use it on my 75g.it is a 6 way mag drive setup.1" inlet and 6/1" outlets.i got my magnets from http://www.unitednuclear.com/magnets.htm (i got .250 diameter x .100 thick,2lbs pull).the motor is 1 rpm(havent bought it yet but found it at grainger for $80).here are some pics and a video.





this video im turning it by hand and shows it is a mag drive(you can see slipping but it doesnt slip when all together)
