I am planning to start Piano lessons asap. I will be learning on an acoustic piano but want something for home so that I can practice throughout the week between my lessons, aswell, as I have some form of "homework" each week. Budget is of some concern, I have 500 dollars I can invest into this DP but that will have to include anything else I may need (stand etc).

Anything in that price range I can look into with 88 weighted keys and decent Grand Piano sound. Thank you for any advice you can give.
