Panasonic SDR-H18 vs. SDR-200 Hard drive Camcorder?

Hi - We're a first-time buyer who wants a hard drive model (not a high-def since we're novices). We'll just be using it for routine recording of holidays, birthdays, family vacations and our little boy growing up. We've narrowed it down to two contenders:

1) Panasonic SDR-H18 which is a Consumer Reports "Best Buy"

2) Panasonic SDR-H200 which is the next step up

The SDR-H200 costs around $150 more than the SDR-H18. The main difference seems to be that it has a higher resolution with 3CCR imaging technology.

My question is: practically speaking, is this resolution difference important enough (for users such as us) to warrant stepping up to the SDR-H200? We basically want an easy-to-use camcorder with average-to-good picture quality in various settings (such as low-light) and the ability to easily burn DVDs without much configuring. I don't mind stepping up to the H200, I'd just like to know that novices such as us could even tell the difference between those two models.

Thank you for the advice!
