Congrats and Welcome to this addiction we call pinball. You should probably start your second thread now "What should my second game be" as this is kind of a potato chips kind of hobby. Only funds and space will slow you down. Enjoy Flash and Know there are many very helpful and knowledgable people on this forum to help you with your first steps of ownership.
PS first game for me was Alien Poker for a Whopping $100 which I still have to this day.
