Just curious to see what thoughts you had one what a really good low-light video camera would be for Tesla Coil videos - at least in your experience.
I've tried a Canon DSLR Rebel I have (about 4 years old) as well as a Canon HD Camcorder (again about 4 years old), but not particularly happy with either in low-light situations.
Was thinking of upgrading and trying something new. Maybe even the Hero 3 as I could also use that for other things.

Hero 3 Black is a great camera with some flaws, it is not very good in bad light.
Here is a comparison between Hero 2, Hero 3 Black, Sony RX100 when filming in really bad light, Sony RX100 is a great camera and has full manual control of all parameters even when filming.

Thanks Mads! The Canon 5D is sweet, but yes, above my budget. I may end up going with the Hero 3 anyways. I only need for a little bit of product photography, but can use it with my kids for outdoor action photography such as kayaking, hiking, biking, etc...

I've never been completely content shooting videos of coils. I think I've realized that the solution is to spend a ton of money, and that's just not what I wanted to do....
Years ago I settled for a Sony HDR-CX100 and I would only call it fair. The high speed recording sucked...
I've borrowed a few cameras trying to find the holy grail, but I have not. One person shot my coil with night vision. I didn't care for that too much, but it you are curious as to what that looks like, here it is :

It's not so important, which CMOS type of matrix you will be use. You shouldn't use CCD, it can't give good result. First thing is the lens speed. It must be <1:1.4-1.8 If it not, you take tiny spark and dark ambient. In 1:1.4 spark will be bright and ambient will be able to see. Canon EOS 100D and ~$500 lens will be fine. See for example "Tesla Music Band - David Guetta - Baby When The Light" video on my channel. It's on 1:1.4 lens speed. In compare with "Tesla Music Band - Dmitry playing guitar", it's on 1:3.5 lens speed.

I believe sound is just as important as the video when recording tesla coil performances.
I'm using the latest hi-end Canon DSLR with an equally good lens. Although it does make for excellent low light video recordings with minimal noise/artifacts, you must use external microphones to achieve a sound recording to equal the video quality. The camera manufacturers never disclose these important details. News crews know it all too well. You can spend $2k for a good camera, and you're left with smartphone quality audio if you use their built-in microphones. The audio noise (background hiss) level is pretty high on some cameras I looked at, so you have to research it carefully. Microphones won't fix that.
Eric's latest dubstep video was recorded using this camera along with remote studio condenser microphones on suspension stands. Placed with a spread of 20' from a 40' wide audio source. A balanced line converter at the camera converts the XLR signal to a single-ended output at the camera's remote microphone input. AGC is disabled to help recover the dynamic range that makes a coil performance so spectacular in the first place. Of course, if you're listening to it on a smartphone speaker then it does not matter . Headphones will provide the channel separation and bass depth of the original performance.
