Digital piano for a beginner

[Nat]

Dear everybody,
I would like to ask whether you think a beginner child student should start with:

-a weighted keys digital piano or

-a graded keys one is good enough.

I just think it will be more difficult (on an acoustic piano) if a student takes an exam in a year or so, and pricey to upgrade.

Thank you very much.

I'd try asking this on the digital piano bit of the forum as well. I can't help you - I only know about pianos, sorry! But I'm sure someone will be along in a minute who can help you!

Thanks Gill!
