search/replace in many files

What is the best way to recursively search thru a directory structure and search and replace text in files?

For example, if I wanted to search thru all files with extension .txt and replace all occurences of the string "red" with "blue".

And write it back out to the same file?

for file in `find . -name '*.txt'`
    do sed 's/$SEARCH/$REPLACE' < $file > $
    mv $ $file
Test it on a copy first.
