The cheapest way is to buy the Remastered Columbia/Legacy Edition available at any major CD selling store. It retails for $11.99 but you can often find it discounted for less than $10. Used CD stores should have it even cheaper. You want the 1997 edition that has the Bonus tracks because Columbia issued at least two editions before. See Amazon.com and see all the comercially available editions without scrounging among the "collectables". All the earlier recommendations are good but more costly and for the fanatical audiophile.
