Canon cameras can be scripted using chdk and I use this to take a photo of my taiko performances once ever 10 seconds so we can have something to post to facebook. I bought a super cheap, old, used canon to implement this but it was starting to flake out on me, so I decided to see if the staples $50 off clearance cameras would work for me. I tried one staples, and didn't find what I wanted, but on the way home from the gig I decided to up my budget a little bit (I was hoping for something sub $50) for something that had a better chance of taking good action shots in low light with no flash. On the way home from today's gig I dropped in to the staples and found a SX40 HS. (The staples was mobbed with back to school people.)
Normally this is a ~$320 camera, it rang up at the cash at $209, the sign, however had said $157, so the manager changed it to $150 and then my $50 off coupon brought it to $100.
I'm not sure how well it will do in low lite, despite the larger lense, but the noise at high ISO isn't so bad. Though it's max iso is 3200.
I will have to see how it performs in the field.
