I recently added some free Dolch sight word resources onto my site, including listings of the base 220 words and 95 common nouns. It is estimated that the combined listings account for common words that occur in 50-75% of children's books.
You can also access colorful word cards divided into grade levels, which can be printed directly from the internet browser. Includes some good ideas for classroom implementation.
