The best organic produce to purchase

I would love to buy organic produce, but I usually don't due to the expense. However, I have heard that their are certain produce items that are more laden with pesticides so I may try purchasing those "dirtier" items organically when I can. I found this blog post that lists the "dirty dozen" produce items and the "clean fifteen. " Check out the "Cent"sible Sawyer blog for more info.
