Oppo was last sold officially in 2017-2018. After that given there is lack of tech support if needed, many were selling it and moving to other brands like Panasonic or Pioneer or Sony given tech support is available.
Nowadays not many want to have a player as part of their setup as almost everything is online. As for me I do have a OPPO BDP 103 which I hardly use but occasionally play some CDs or use the USB to watch some content rarely once / twice in a month just to keep it running.
You can try with service@oppodigital.com. they're really helpful.
Earlier I enquired for my bdp 95 player. It was for a laser pickup and they were ready to send it (from US). I just dropped the idea because it was coasting some 10k there but the shipping and customs duty will be huge.
If you are ready to pay some serious amount of money its possible.
