Even though I have never been a keyboard player....

I tried to learn keyboard..being the guitar player I was.

Here's a bit of history:

Roland 88 key: My kids were around 10 years..1988(???)...had to convince the first wife digital keyboards were the future.

Casio Privia 88 key 2004: my grandkids have this one

Yamaha Psr E423: My grandkids have this one

Yamaha Psr S710...I started playing left hand chords...learned what these arrangers can do. Traded for Psr S950..mostly for harmony...

Sold Yamaha Psr 950...got a friend...guitar player/singer bought it from me, trying to learn as well.

Tyros 4...Found out I could be a one man band...sort of.

Tyros Psr s750...had a PA...traded even up.

Perhaps I will trade the S750 for an S950. Maybe I will try to trade the S750 for an SD7??

The SD7 has bugs but has a lot going for it compared to other keyboards..love the on-board speakers...wish any Tyros had that.
Compared to any other instrument(I've paid many $$$ thousands for instruments) price wise for what it can do...It's a steal.

By the way, the Tyros is a steal too.

That said, I think I would buy an SD7 at this point.

Best of luck.
