git client for Windows

We're starting to try out git at work to potentially replace Subversion. I've been using git for a month or so at home for personal projects, but that's been on a Mac where git works natively. At work I have a Windows PC, where git is less comfortable. Obviously if we're gonna switch to git we all need to be able to use it, so a quick search for Windows clients led me to a couple. git-cheetah is in development as a TortoiseSVN-style Windows Explorer plug-in. Here's its readme:

"This is an explorer extension in its infancy.

UPDATE: I've just written a new post as now there is a GUI client for Git on Windows.
