I agree that you need to buy for the game you're going to play. I recently bought a no-mold set so that I could have a set with nickels. I have some people that want to expand their game choices, but, want to learn at lower stakes. The no-mold group buy allowed me to do that on the cheap. If you don't think you'll ever use the micro denoms then you're just taking money away from another potential set purchase.
