For freebies InstaDMG http://www.afp548.com/article.php?story=20090812091929480 and DeployStudio http://www.deploystudio.com/Home.html with Radmind (if you need it). For pro stuff try Jamf http://www.jamfsoftware.com/. Join the system-imaging list with Apple. The people on there are far less 'flamey' than on the OSX server list and will be able to advise you on the different tools, their experiences etc and really are helpful.
