I always recommend Harry Lorayne's The Magic Book. It is not as comprehensive as the Wilson book but for someone starting out makes the entire art accessible with a few well chosen effects and sleights. In addition, Lorayne is, imo, probably the most clear magic writer.
Learn the sleights and effects in this book, along with a good presentation style, and you could make a career without ever buying another magic item.
That said, I think there are a few complaints about Lorayne not always properly attributing some of the effects.
