Piano/keyboard recommendations

I bought the Casio CTK-1500 keyboard a week ago and have been learning to play it. I am making progress and am starting to realise that this keyboard is very limiting. It doesn't support a sustain pedal and I feel the size could be bigger (it has 61 keys). I guess I bought it because it was cheap.

I am having second thoughts now, I am still in the returns period so can send it back and get something better, though I need advice. Any pianists care to advise?

I ended up replacing the Casio with the Yamaha NP12, as I understand the P45 is one of the best keyboards out there but even a used one is out of my budget.

The NP12 is working great so far with touch sensitive keys, sustain pedal support and non of the unnecessary sound effect features. All for less than £200 brand new.

Now I just have to keep practicing!
