AlienBob has binaries of his slackbuilds for download and the Microlinux Desktop (Nicholas Kovacks) provides a range of binary builds for a nice xfce4 desktop. 14.2: microlinux builds are on hold a bit until 14.2 gets more stable.
There is also the slackonly binaries that are built from the slackbuild scripts at slackbuilds.org. Not sure how maintained slackonly is but many of the 14.1 builds work fine.
You don't have to compile a lot unless you want special options or if you have trust issues about binaries.
