FRAPS will work the best, I have tried all the others, it uses a lot of space to record, I record at 1920x1080 at 60 FPS, and it's ~4GB per 1 minute of footage, depending on the game.
I have ~1.5 hours recorded, and it's ~300GB. If you don't have a decent size HD, then you will need to convert the clips, or record at lower frame rate.
