It is an amazing thing. I skipped the CD-ROM motors phase, that was just ending as I got into all this. But I still like old CD and DVD drives too because I get two free 3mm shafts out of every one. Almost every old computer goes to the graveyard with at least two 3mm shafts and a CD-ROM motor in it!
You know about Strong Motors? He still has some of the bits and pieces that made for some of the best CD-ROM motors. Don (bz1mcr) is a regular here on the forums and a gentleman to deal with too.
