Here are some places where you can get good website templates. Depending upon what you're running your site off of, however, not all of them will be suitable.
If you just want an HTML template to work with, you can check out FreeWebsiteTempates.com. They're near the top of the search engine rankings for a reason.
Other sites include QuackIt.com, InstantShift.com and 2WebDesign.com.
There are pages upon pages of templates to choose from at these sites, but you'll have to work with the HTML Code to use them.
