Viewing a PDF with links on iPad Are there any (hopefully free) iPad apps for viewing PDFs containing links?

For instance, I have a long PDF with a table of contents in the beginning containing links to later parts of the PDF. These links work when reading the PDF in Preview on my laptop -- when I click on the link for a specific section, the Preview jumps to that section.

Unfortunately, on my iPad, none of the PDF readers I've tried so far support this functionality. Are there any apps for the iPad that work like Preview?
GoodReader is not free but supports linking.
