How important is it to have weighted keys to learn piano on? I think most of the pros/virtuosos/Jordan Ruddess use weighted keys for their stuff...what is the advantage of using weighted? I know it helps build finger strength which is why I'd like to start with one...but I'm moving out soon and I'm not sure I'd be able to take a fully weighted piano with me. And most fully weighted keyboards are pretty expensive, so that's most likely not an option. I'd like to keep the cost of a piano around $500 - $600. For that price I figure I can get an old used upright piano or a cheap MIDI keyboard.
