What is the best kind of keyboard to buy that most resembmes a piano?

I am going to begin taking piano lessons but cannot affod a piano. I would be able to invest about $400 into the keyboard. Full size, of course.

Best Answer - Chosen by Asker: Just off the top of my head, the link below will fulfill all your requirements for now. You will want to upgrade eventually, but the keys are weighted, the action feels fairly real, the pedal is horrible and you will want a better one, you can practice with headphones on late at night or when someone is watching TV, and it is extremely portable if that is an issue or becomes one.

I use a Casio Privia 500 in my classroom and have another one at home. I also have a Yamaha PSR 6700 that I used to gig with, but the keys aren't touch sensitive and even though it is a much better keyboard, I find myself using the Casio most of the time. Hopw this helps.,
