I'd agree. The iSight is way better in low-light situations, and its FireWire interface provides a very clean, fast 640x480 image. Most USB webcams still produce low-res or choppy images (though surprisingly, Apple's built-in iSight cams in their new machines are internally USB-based, but still work very well).
More expensive, yes. But as said above, you do get what you pay for in terms of quality.
To save a few bucks, you can always check out eBay now that most of Apple's machines include them.
