The amount of $$$ you will have to spend depends on the condition of the cards you buy, and therefore will vary widely.
Personally, my advice for sets this old and expensive (and the strategy I follow) is to focus on centering rather than corners (since bad centering detracts from the visual appeal more), and to focus on cards in the EX to NM range (i.e. PSA 5 to PSA 7). Buy graded cards if you find ones you like and crack them out, but don't pay a premium for the label.
