All Things 88?
If you’re keen to play piano, then you’ll definitely want to make sure you get a piano with an 88 key fully weighted action. You can of course start learning on a keyboard with less than 88 keys that aren’t weighted. This seems to be ok initially as you are just starting to get familiar with the notes and the placement of your fingers on the keys.
The downside is that you are not going to get any type of technique developing. This is because there is a big difference between just having springs for resistance in the key action (non-weighted), as opposed to having progressively weighted keys with weights in them (88 note fully weighted action).
Years ago, this would have meant splashing a LOT of cash, but these days 88 key models are more affordable than ever.
