Git or Cogito are not that terrible to use, and, in fact, they're quite pleasant to use. Their shortcoming is that they're not very portable (at least to win32 native) or there's little effort in having an usable win32 binary. Mercurial has proven very powerful and it's really concise and easy to use. The Xen people are using it and I do it myself with home grown pet projects... without any hassle. I would tell you, give it a try!
