Don't geta keyboard. Getting Keyboards with weighted keys are usually quite expensive and then you'll have to buy a good pedal too.
I'd suggest buying an Ellington upright piano.
They are beginner pianos and are relatively smaller than most pianos and contain less keys but the amount of keys it gives you is fine for a year or so.
If you do have your heart set on getting a keyboard with weighted keys i'd suggest buying a cheap electric keyboard until you can afford a better one. For the first 6 months of me learning piano all I really learned were some chords, finger exercises and really simple songs so playing on a cheap keyboard would be ok for a little.
