Please dont got with cheap....... youre just asking for trouble
stick with a name brand and read some reviews on the card and what the reviewer was using it for.
Yeah, I got a 4gb generic flash drive off ebay for $7 a year ago, it completely crapped out when I used it to make a Google Chromium boot. I literally tried everything to fix it, it's dead. Luckily it was only $7, but if I had paid an extra 5 bucks to get a name brand it'd probably still be working fine.
You can't go wrong with Amazon.com for a brand name like San Disk and you might even chech shop CB.com right here on this site as they sell 16gb cards too.
