Photography purposes, huh. I know of a few:
Samsung TL320 $299 (good in low light situations)
Fujifilm Finepix F200EXR $399 (automatically process your images to reduce noise or increase dynamic range at the expense of image resolution)
Panasonic Lumix LX3 $499 (they have a sale at amazon for $319! Also can shoot in RAW mode which is great for photoshop enhancements so its similar to a $$$$ dslr)
Canon S90 IS Price: $425 (most expensive but comparable to the Panasonic's abilities, most pocketable)
I'm actually a bit biased between the Panasonic & Canon, only because they're closer to a DSLR's level. xD
