Tyrus;
You should buy a PDA. This has saved me lots of money on not buying chips I already had. If you do get a PDA you should download firepad from firepad.com. This converts jpgs and other graphic files into palm computing format and syncs them with your computer. I loaded a bunch of illegal club chip images onto my PDA so I could get help in identifying them at the convention, however all the illegal experts that I found could not ID the chips and a few wanted to buy them.
