>Basic Fantasy RPGMy personal favorite. Essentially Moldvay Basic with race and class separated and ascending AC. Has a lot of community support and free supplements, tools, and adventures. Also one of the few retro-clones to be explicitly specified as open-source.

>Labyrinth LordA retro-clone that adheres closely to B/X D&D. Has an Advanced Edition that allows for a lot of stuff from AD&D.
