If you're looking for very low cost, have a look at the Casio EX-Z1050. It's a 10.1MP compact with a larger than usual sensor, and really does produce remarkably good results for the cost. I just got one for use as an aerial photography camera, to replace my venerable Canon Ixus 4MP one, and I'm pleasantly surprised with the results.

It's also got an enormous battery, despite the very low weight (145g including battery and card), which seems to go on forever. In continous shot mode, it managed one 10MP shot every 1.4 seconds, which put 1000 pictures on the 4GB SDHC card before it ran out of space, and the battery still read full!

Not bad for a camera that's available for less than £100.
