I just recently redesigned my company's website and one of my main objectives was to make my product download pages look like the rest of the site. Here's a screenshot of what the download page looks like now. This is simply E-Junkie's "i-frame" solution being displayed with some custom CSS on a redirected page hosted on my site.

We provide custom UI templates and design services for touchscreen-based automation systems, so no worries, I'm not trying to sell anyone anything (unless you happen to be part of the one-bazillionth of the population that is our client base). I just saw several posts (from people who seem to know a lot more about web design than I do) expressing frustration with the options for displaying download links in their redirect page. I don't know what they're wanting to do, but I was able to accomplish this without any extensive knowledge of Javascript or PHP.
