I always try to be careful with stuff, but I usually tend to get stuff that doesn't need to be taken care of too much. e.g. CRT monitors, stuff that isn't shiny, stuff that isn't flimsy.

It is hard to be careful with CDs. I don't mind minor damage as they are bound to get a bit scratched eventually but if the CD belonged to someone else I would be more careful with it. Alot of my old tapes (VHS and audio) are in much better condition than alot of my CDs.
