Does anyone know the obvious differences between these two systems. I was looking to buy the 210 model, as I saw it on the Panasonic website, but although websites are offering it no one seems to have it in stock (unless I want to pay over the odds) - that and it's discontinued. However, I have seen the 200 model in a few places, and in stock, but by going for it I feel like I'm getting less for my money - just not too sure why!?
