Hello, I am very interested in getting a piano, but I don't have much space and I have to move it around because I don't stay in one place forever.

I was thinking of getting a weighted keyboard, 88 keys full set, I don't mind if it is second hand.

Any website or shops that you can reccomend me?

I can recommend Yamaha digitals. I've had one for nearly a year and love it!

M-Audio digital pianos or keyboards are also good for your practice.
However, be aware that its keys are made of toxic materials from China hat may cause cancer or birth defects.
Many toys from China have been recalled and discontinued, but M-Audio products are still on the American market.
