Hmm, I can't say I know of any deals, but usually local shops carry used Sony cards that you can pick up on the cheap. At least there're tons of local shops in NY (not eb or gs). As for using memory additions/expansion tools (specially from Intec), I would say stay away unless you want to lose your precious data. If you're looking for a serious backup utility, invest a little more into a memory manager that can be found at import retailers like ncsx. They're not cheap, but they're very reliable, and allow you to have infinite space (well as much as your computer will allow)
