Screen Recorder wanted.

I know there have been many threads about screen recorders, but i couldn't find one which tackled the problem i'm facing.

I need a screen recorder that can record duel audio (aka my turtle beach microphone and the computer audio) and is preferably free (but an can pay if i have to). All the free options ive tried have either covered the screen in bloody watermarks or have produced terrible quality audio and video. Screeny looked nice but there in no info on the website about audio. Thanks for any help.
