sound card for laptop

[drummerdude]

i've been looking for a sound card for my laptop and i dont know what my best option would be:
option 1: find a usb sound card
option 2: do expresscard sound cards exist?
option 3: if they dont, just get a pcmcia card and get an adapter for it like this link

does anyone know what my best choice would be, and make some recommendations?
