P45 VS P105

[newtopiano]

My child has mentioned a digital piano for Christmas and I would like to learn piano too. I’m unsure if either of us would do grades exams.

I read (mainly on here) that the Yamaha P45 is an excellent choice but I have noticed a cheaper, closer P105 on Facebook Marketplace so I am just wondering if I should try and purchase that instead of the P45? Google isn’t clear which is the better model!

TIA
