Looking for Sony RN-DX450 remote

I need a replacement remote for my very old Sony CD player. The remote is a Sony RM-DX450. I have searched to no avail. Sony says that a replacement remote is no longer available. I can purchase a new CD player, but the old CD player works just fine other than the remote. The Sony remote is of, what I would call, a "two way" or "feed back" nature,, i. e. it has a display that shows the info of the CD that is playing, etc. I have tried the codes for Sony CD players in various learning remotes with no luck even for basic functions such as play, pause, skip. If anyone has any suggestions of a work around or the availability of a replacement remote, I would welcome any and all.

Regards,

Thank you very much Edmund. At $120 for the remote and a new 300 disc player at $170, I will have to think about this for a bit and keep looking for a less expensive solution
