What is the best "inline frame" plugin?

I have a need to feed an inline frame to a website (I know ... I know ... no SEO commentary please). :slight_smile:

I am working on a jewelry website and they get their watches from a dealer who has a white-labeled/generic site with watches on it. We want to show that info inside their 'watch' page.

Any suggestions for an inline frame plugin?

AND/OR ... I will be designing the watch page. Any suggestions for a simple system that will feed and update the inventory from the watch site to the WP site that I'm creating?

Thanks in advance.
