Great for the price

I bought one of these specifically for hacking it as a time-lapse camera. I paid $19 for a refurbished camera.

As a hackable cam it is very easy to deal with - apply power (and it isn't too fussy anything from 2.5-4.5 volts is fine) and it comes up ready to take pictures with the feature settings you last put in (like resolution, flash on/off)

They sort of imply that the largest memory card it will use is a 512 MB card for ~900 pictures maximum, but I'm well over 1000 into a 1 GB card - only downside is it seems to take longer for a picture to go into memory as the card fills up.

Picture quality is surprisingly good. Easily as good as my old HP camera that cost me ~$200 7 years ago. I'd definitely recommend it. Batteries last a very long time (my hacked version can take 1,000 pictures over four days on one set of 3 rechargeable AA size batteries, so 2 AAA alkaline batteries should last well over 600 pictures). I doubt there is any CCD camera that can make that claim.
