We have an electric piano with weighted keys for the three years my eldest has had lessons for.
He has just done grade three, in the practice room they had an acoustic upright. He played the pieces well on it, but as he was taken into the exam room he was shaking his hands and commented after about the difference in playing.
His teacher has said it's probably time to upgrade the piano. Any advice or recommendations from people who know what they are doing? I know I could get a second hand one very cheaply but I'd have no idea if they would be tunable so I'm not sure if I should just bite the bullet and buy a new/reconditioned one with warranty.
