these are the ones i have, http://www.jegs.com/i/Accel/110/7054/10002/-1 the problem here is that they are for male terminal distrubtor cap. so for them to work on your car you would need this http://www.jegs.com/i/MSD-Ignition/121/8414/10002/-1?parentProductId=747895. that pretty much spends the 150 you save on the coil.
"Business card" size. Very low capacity, but very convenient for handing out at trade show booths, with business cards, etc. Pocket friendly. And of course they only work on CD drives with trays that have the small inner circle indentation, or laptop type with clips. But these days that's most of 'em.
and now let me teach you some more, don't shove one of those things into a laptop with a CD slot, will just get lost in there . . . you may then have to get a paper clip and get creative! lesson learned . . .
