Looks like the new kid on the block AutoDMG will be superceding InstaDMG as the preferred image maker of OSX clean never booted images. It’s currently a development product nearing a final release. It has a GUI front end which makes it super simple.
It’s hosted on GitHub and you can download the latest 1.4.4 dmg version here file here. Make sure you keep updated with the latest versions.
When building an image with AutoDMG the OSX version you are building on must match the image build – so building an OSX 10.9 image must be built on a OSX 10.9 Mac. AutoDMG can also build OSX 10.8.5 images. The OSX Yosemite 10.10 guide is here.

When the installer is finished downloading it will prompt you to install, just quit as we will be using the installer to build the image.

AutoDMG downloads any incremental updates.

All too easy!, you can deploy with DeployStudio or direct to disk with ASR.
With Apple Software Restore you can image a disk directly from the Terminal:
sudo asr restore -source osx_custom_131102-10.9-13A603.hfs.dmg -target /Volumes/test/ -erase -noverify
Change the source and target to suit.
