I'd like to have the links in a separate file, so when I need to make changes, I only have to change that one file to update the menu wherever it appears.

I'd like something simple, with a small footprint in the HTML on the individual pages. The one I have always sits at the top of the page, even when scrolling, and I think that's a nice feature.

It doesn't need to be fancy, perhaps just change fonts and colors, and I don't need multiple levels, just 5-6 links that display initially, then a drop down or something when they're clicked on or on mouseover.

I've been searching for the last few weeks, and I also searched here, but thought I'd ask before I invested too much more time. I don't mind paying for it, as long as it's not hundreds of dollars.

I have searched some of the bigger sites that offer these scripts, but haven't found anything that meets my needs, is easy to install, and doesn't require a lot of time to implement.

I'd like it to work with all the popular browsers.

Thanks in advance for any ideas and suggestions.
