Instructions
Decide whether you want to find an antique player piano to restore or if you want a complete, working one. If you are looking for a complete, working antique player piano and do not know how to repair them, make sure you have a player piano repair person or company near you.
Consider buying a conversion kit to convert your normal piano to a player piano. This is an option, though it doesn't satisfy the need for an antique player piano.
Check your local classifieds. This is an especially good place to look if you're living in a large city or a city with lots of musical influence. Remember, always look at the condition of the piano before paying for it.
Browse online selling sites (ebay or sell.com) or online piano enthusiast sites, like Player Pianos. Keep in mind that you will have to pay a large amount for shipping because of the weight and fragility issues.
Contact local musical instrument stores and schools to see if they have any antique player pianos that they are willing to sell. Be sure to look for damage or wear and tear to negotiate a good price. If you are unaware of these things, take someone who knows what to look for.
