I am currently seeking out a busted TG CD ROM.  I really just need the outer casing so internal workings are of little concern for me.  Of course, I would be interested in a functioning unit if the price/ trade is right.
I have also been on the look out for a PCE Duo or TurboDuo that has issues or a non-working CD drive.  I have a PCE Duo with a perfectly working drive and want to try and combine parts to have 1 good unit.
