Currently I am making photos with my Eten M800 cellphone, and they are fine outdoors with good light, but terrible indoors with poor lightning. I would like to buy a camera which can be better at it, and not spend more then about 100 EUR / 150 USD on a used one from eBay.
I've used a Sony Cyber-Shot DSC-W270 a few times, and it makes excellent sharp photos even in poor light, without the need to set anything, and costs about 100$ used on eBay, but it uses Sony MemoryStick cards, and I'd much prefer something using standard SD cards.
As I like hacking things, playing with firmware, I'd prefer something where I can install CHDK so something from this list.
I've seen good reviews of Canon PowerShot S90, but it costs cheapest 160 EUR / 220 USD, but that's about twice as much as the Sony Cyber-Shot DSC-W270 - is it really that much better to be worth the money?
Because I have the habit of occasionally getting my electronics in wet or dusty conditions, I'm also looking at the Canon PowerShot D10 waterproof camera.
I'd like people not too have red eyes if I shoot with flash indoors, and be able to photograph the underside of my car reasonably sharply without looking into the display.
Is there anything else in that price range that is exceptionally good value for money?
