I'm sure you most likely know already, but for anyone that doesn't, there are such add-ons out/supposed to be coming out for the above two. The BacPac LCD screen is $90 at RadioWorld, comes with replacement hatch doors to fit it into the case; of course this makes the camera a little bulkier than it already is, but I'd gladly sacrifice that for the ability to quickly line up my shots, or to review video while away from the computer. There's supposed to be an external wireless mic coming at some point(???) but haven't seen much about that.
That said... yeah, I'm really not happy at all with how the GoPro is handling night-time video. My ContourHD is definitely better for that, and I really don't want to be switching between them, since the GoPro is clearly superior in decent lighting. Hrmph.
