I've got a set of 5 Panasonic C140A's and 4 C101A's, and for the price, I'm happy with them. I got them on sale at amazon, about $125 for the C140A's and $55 for the C101A's.
For a few of the cameras, I've also got motion sensor flood lights set up so I can get a decent image at night. With just street lights, it's not enough. Even with the flood lights it's a bit grainy, but ok for me.
I've got it set up to ftp images on motion detection, and keep a monitor up with a real-time feed for all 9.
They use a proprietary POE device, and I think it's important to use good quality cat5e cable. At first I bought some cheap cat5e cable and found the POE didn't work so well. I discovered that 2 of the pairs weren't actually copper. So I had to have the cable ripped out of the walls and conduit and replaced. With good quality cable it works fine.
