Show a product on a non product page

I have been trying to figure this out - I have a typical page created via MANAGE PAGES and on that page I want to show a product for sale.

I am just trying to figure out how to include the product image, and product info so the rest of the add to cart all works.

I have no troubles updating the pages_details.tpl to just go into this loop for a certain hard-coded page.

Has anyone done this?

Many thanks in advance
