Waiting for a5x2? Buy nomad? Other alternatives?

Hi guys I'm looking for a new device to take notes and I think supernote would be my preference, mainly for the gel pen feeling and the note searching feature.

I think the nomad could be too small, but it doesn't seem that the a5x2 is gonna be launched soon.

What do you recommend me? Wait? I have seen a second hand nomad (almost brand new) for 415 eur and I am doubting it. Apart from supernote, what other options do I have with a similar writing feeling? Thanks in advance!

PD: Another option can be buying a second hand a5x. Does it exist much difference between the old and new model?
