Suggest you buy a used unit with weighted key (unless you sure will not play piano) otherwise check out different showroom they always have showroom set for sale at discount. Luthermusic clearing a showroom NP11 for SGD$ 199 (show room unit) only soft touch key, piano sound is like the PSR-423 (not great but still better than those low cost keyboard). Was there to buy accessories yesterday. Nowadays digital piano (that has many voices/rhythm) with weight or Graded Hammer Key about SGD$ 1.2K to SGD$ 1.5K brand new and is impressively good already.
