newbie help with 4MP for close-ups & movies

[danc2]

Hi all,

I'm new to the digital camera scene, and I need some help choosing a 4 MP point-and-shoot camera.
I recently borrowed a Nikon coolpix 4300, to take some shots of my car, for advertisement purposes. I was very pleased with the results. The only thing stopping me from buying this exact model is the lack of sound while recording short video scenes.

Here's what I want to use the camera for:

Taking close-up pictures of mechanical parts and assemblies, indoor shots mainly, sometimes dull objects in poor lighting.
Recording short video scenes with sound, that can be sent by e-mail.
I also want one with affordable memory.
Also outdoor shots, cars ,buildings, animals etc.. nothing too sophisticated.

Size/weight is not too important, bearing in mind I'm new to cameras, which of the following ‘best camera' would suit my needs:

Canon Powershot A80

Panasonic DMC-LC70

Sony Cybershot P73

Casio QV-R40

Konica Minolta DiMAGE G400

Kodak CX7430

Olympus D-580 Zoom

Thanks for any help,

Danc
