I've a CP5000. Its a very good digicam, especially since you're looking for a small, compact DC with high performance.
It also have a whole range of function associated with a high end consumer digicam. This will allow you to grow with your camera.
Most people would say this DC is a bit over-priced. I wouldn't entirely disagree. But I look at it for the fact that it's very compact & the ergonomics is the best I've seen for a consumer digicam.
You won't be disappointed.
Alternatively, the common opinion is that for $1.7k, you should go for Sony's F707.
As with all digicam purchase, you'll need to set budget for extra battery & memory.
CP5k batt cost about $70, and a 256mb CF is about $180
Similar items for F707 is more pricey, but f707 impress in its performance.
G2 is more known as a value for money product. Even though its only 4mp, it doesn't really lose out to 5mp digicams.
Any other queries that you have?
