Most boards come with micro sd slots. Some screens have full size sd card slots - I've got a couple of these plugged into my two mashines that have micro sd card slots.

Plus you only need a small old sd card. My sapphire pro card is 2gb - currently got about 50 sliced models on it for a total of 184mb :-)
I'll wipe it soon as it gets a pita to keep scrolling through to find the print you want.
