Hey all!

         I aspire to become a great Ruby as well as Rails developer. 
But what books should I buy?

         Is this a good mixture? For instance, with 02, do I really 
need 03? Or with 03, do I really need 02? Please give me your input 
guys. I don't have too much money to spend.

Thanks,
Kyrre
