Hi, I need some suggestions on which type of piano I should buy. Should I get the 61-keys keyboard to learn to play the piano first or should I get the full keys piano ?

I'm new and planning to teach myself how to play it. I used to play some simple songs but it's too simple even my grandma can play.

So, if I get the 61-keys keyboard, am I able to learn most of the songs ? I don't expect to play like those experts who plays those almighty classical music, I just wanted to learn and play those current pop or rock songs as a start/newbie.

Also, which brand and model would you suggest? Thanks sifus.
