Well James, I see you're still at it :) But you've got it down to 2, so that's not bad.
I didn't catch (or forgot, I do that a lot) where you mentioned exactly what the main use of the camcorder will be, but if its just to shoot basic home videos of the kids in the living room, just save the money and get the Elura.
If you're planning to do anything more than that, you just really can't beat the Optura. Best of all, as your video skills grow the Optura will be there for you. The manual focus ring and manual audio control are just so cool and unheard of at this price point. Honestly, at 400 bucks the Optura is almost worth it as an audio gathering device. And the image coming off that CCD is really top notch - I watch my Optura 30 videos on my HDTV and it looks like a TV show.
The whole low light thing is just a non-issue. Yes, the Elura and many other cams will produce a slightly brighter picture in dark rooms. But honestly, I've actually found that my Optura 30 pretty faithfully reproduces about what my eyes see. So basically when I shoot indoors the video always comes out alright, because I flip on a light when it gets too dark for ME to see comfortably. If I can't see very well in a room, I don't expect my cam to either (unless its a Sony VX/PD series, but that's another horse altogether).
On the plus side, you've reached the point where you probably can't go totally wrong anymore. You could flip a coin and pick the Elura 100 or the Optura 50 and probably be pretty happy and make nice videos with either.
Good luck!
