Hmm...I wonder if a place like guitar center have a couple units that say, they purposely made available just for the consumer to try out, meaning- like you buy it just you would (in this case- we'll call it a deposit), then if you don't like it within 14 days you can return it. So say for about 25-50 keyboards they have, there will be two that they'll 'sacrifice' and then they can just actually sell those keyboard as a 'demo'.

I'm just trying to get myself included in this discussion
