here is a picture of the items I requested from PokerSource:
The Copag cards are of pretty high quality, the best I've played with. They are 100% plastic, have really good snap, and slide across the table well. They also shuffle very well. You will be very satisfied with these playing cards.
Dealer button: pretty basic design, pretty much does exactly what it says it will. The beep is rather annoying, but it serves the purpose. This is more of a novelty and I'm not sure how much you would actually use it.
Acrylic chip holders: work very well, seem of a sturdy contruction, and give even cheaper chips a more professional look. They hold 100 chips each, which is actually a lot more than it seems, but makes for fun because players can start with more chips.
