I used a universal projector mount from http://www.mountdirect.com/PMS_Projector_Ceiling_Mount_p/pms.htm the PMS Series Projector Ceiling Mount. Got it for $39.95 it also comes with a free extension kit. It looks like and off brand but the build quality was very solid. I choose the white version to better match the Optoma HD32 projector better. It was universal mount but did not list the Optoma HD32 instead it listed its clone HD70 since there the same projector I just bought it.  Low and behold it fit perfect I guess thats even a little more proof the Optoma HD32 is just a reapakaged Optoma HD70.
