That's insane. Even now they're going for over $300. The 203 and 205, last I checked, were selling at a premium over list. Crazy. But at the time they were discontinued there wasn't much serious competition in the high end 4K player market. I wish I could have had a last run 205, but my current circumstances couldn't justify keeping a $1300 player, especially when I still wanted to keep a 103 or 105 for some of its unique features.
Used to be one of the big selling features of Oppo players was being able to replace lost/broken accessories very reasonably. I bought a new wireless dongle for my 95 very cheap (it's not the same as 103/105) and other accessories over the years and their customer service was second to none. If you need anything that they still have, however, order it now as it appears that once they're gone, they're gone.

It is heartening that I see they're selling both new and refurb remotes for the 8x/9x players. I might order one for $8 as mine has some minor flaws. They were OOS by the time I got my 95 so I had to get a new non-backlit one until I could find a used backlit one. So maybe they will occasionally have things.
I would definitely get the wifi adapter if you don't have it. It looks like they're already OOS on the extension base. Reason for having the wifi is if you ever decide to use it to stream music from a NAS you will want it, although you will need a monitor to work it. And if you ever go to sell it, buyer will probably want that as well. It originally shipped with a power cord, HDMI cable, remote, WiFi adapter, WiFi adapter extension base, all in a black Oppo box. Also had a black Oppo logo tote bag that the player was inside. I have all the packing for one of my units save for the original manual; the other one I just have the black box and tote bag (I bought both used.)
Edit: I'm an idiot. The WiFi adapter they still have in stock is for the 9x, not the 10x. I was thinking 95 because that was the last thing I bought from them, but you did clearly say you had a 103. Sorry if I got your hopes up. They are not interchangeable, as I tried to use the one for a 103/105 on my 95 to test when I first got it, and no go.
Edit2: one nice feature of the Oppo I didn't mention is the ability to use it with an IR blaster output without having to stick anything over the IR receiver, you can just use a mono headphone cord direct into a jack in the back of the unit. I am actually using this feature on my 95 as I am using a two zone Luxman preamp.
