It's like playing the lottery-odds are you'll never get a card you want.Some reputable dealers are Kevin Savage, Kit Young, 707 Sportscards, Larry Fritsch-Google any of them. Ebay is an option, but beware and bid carefully. Get a Price guide like Tuff Stuff or Becket and learn about conditions and pricing, and learn how to bargain.
