Cheapest I know of is the Unibrain Fire - I for around $120.

Fun to play around with, I've got one at home.

The bayer filter really wrecks havok on the image quality in low light situations. The Color Checker image is illuminated by a lamp sitting 4 inches away from the color checker (hence, best case scenario). In addition, very high light situations (full sunlight) seem to not go well either (I work on a robotics team, and we use a pair of Neutral Density filters totaling +6 to decrease the incoming light).
The only other Firewire cameras I can find go for a minumum of $400, and basically have the same image sensor as this one. I'm not saying the image quality is great (It is, basically, a webcam), I'm saying it's cheap and it's a great way to get started (or play around with) digital camera control and capture inside of Labview.

If you want to use the camera from LabVIEW, you will need the 1394 drivers. I would use the IMAXdx drivers, which are the most current. You will have to purchase the NI Vision Acquisition Software to get them. They cost more than the camera!!!
I agree that this camera is a good starter. I would never use it for any kind of analysis, but it useful for learning how to use a firewire camera. It also teaches you some of the pitfalls of using a color camera - color balancing, Bayer filters, etc.
