I thought it would be nice to have an internal front card reader in my PC for micro SD cards, which are the only kind of memory cards I use. However the only internal card readers I can find are all 7-in one, 21-in one type multi card readers. Do any internal PC card readers exist that are simple, and only have one or two slots for MicroSD? I don't want a bunch of obscure slots for memory cards that I will never have or use.
