there's an unofficial build on xda. personally i stay far away from unofficial builds. im sure the real thing is right around the corner, and since rooting is already available, i can wait...
I'll say that the unofficial one works just fine. I use it without issue. However, I just boot into it via fastboot. I didn't want to flash it permanently till there's an official version.
TWRP is also working, as I've tried it too.
Personal preference to which one you'd want to use. Try 'em both out
As mentioned above, it should also be available through ROM Manager. I'm rooted, but have yet to install a custom Recovery - only flashed Franco Kernel and so far loving the experience.
