Ancestry.com recently announced their Revolutionary War Pensions and Warrants database. They've digitized the film of these records. The direct link is:

The index is not a full-name index. It's great to have the images as close as my desktop, but I'd like to have a little more functionality added to them like they have done with census and other records.
Footnote has the same records on their site with an everyname index. For this set of records, that's the site I'm using. I'll use Ancestry if there's a question about image quality, but for searching I'm going with Footnote for this set of digital microfilm.
