This is the one I use (red filter in salt water, cyan filter in lake/fresh water).

Fits all GoPro accessories except the filters. I got a set of cheap filters and modified them by shaving out one side to get them to fit the rectangular housing (GoPro is square).

Camera $40, filters $7. Here's a link to give you an idea of the quality you can expect
and a snapshot taken from the video (played with VLC Media Player (free))
Note: I used VSDC Free Video Editor to do auto color correction for the video and VLC Media Player to do auto color correction of the snapshot. Both have far more color adjustments than I understand.
