Which Philips Lumea should I buy

[Anothercupofteacanthurt]

I've finally decided to buy one of these magical devices, but am totally baffled as to which Philips one to go for.

I want to use it for face and body, happy for it to be corded.

Any advice? Thanks!

I have a 9000 and it works for face and body. Not sure what the other options were but to begin with I quite liked the app that came with the 9000 and the ability to check the strength of the light (not a v scientific term sorry).
