My wife won an egg the first weekend Paris was open. It came with $1000 cash but no IRS documents. (Thank you!). The egg is hand delivered. We have also hit another of those machines for $500 three times.
Harrahs Laughlin had two machines with matching his/hers Rolex watches several years ago. I don't know if they are still on the floor.
Spacequest came as a set only. The set has been sold from the gift shop for $149.95 plus tax. I bought a set there about a year ago, so I don't know if the information is current or not.
