Which is best way to create a web Flip Book?

I am creating a spec book of about 200 pages and it used to print and go in a binder but now it needs to be on web as a flip book.

Since I do all the production work in InDesign I hoped it could be an export.

I have heard about http://page-flip.com/ and http://www.freshcatalog.com/ but should I have to pay for more software if I can do it in InDesign?

Will a 200 page project be a monster of a file size and would that cause performance issues?

I appreciate opinions on this issue.

Thanks Jim K
