Both devices are from the same supplier, one for 449.- and one for 999.- :) Can't be, I'll contact Philips directly but thanks!

It may be, I think, that there are different suppliers. Hence the different prices. The device itself is the same.

No idea, I have no comparison as I am buying one device and not 2 to compare them!

I don't know, ask Digitec directly or compare it with the number on the Phiipps website. We are definitely satisfied with the device.
