Textpander is a nicely done and free utility for OS X that enables you to insert text snippets based on shortcuts. I used to use TypeIt4Me before, but somehow can’t seem to get it running on the Intel Mac. Peter Maurer’s other software is also worth checking out.
just to let you know that TypeIt4Me 3.0 now fully supports Intel Macs and adds plenty of new features. Check it out here: http://homepage.mac.com/rettore/ty2/TypeIt4Me3.0.html
