It looks like Ebay let's you run an empty search in any category, and then you can filter by higher price.
These are the most expensive items on sale for consoles & video games (https://www.ebay.es/b/Consolas-y-videojuegos/1249/bn_16585397?rt=nc&_sop=3).
And these are the most expensive items when you specify "Consoles" (https://www.ebay.es/b/Consolas-de-videojuegos/139971/bn_16553479?_sop=3), much more interesting as the previous one showed the typical Nintendo cartridges.
And these are the most expensive articles for "vintage computing" (https://www.ebay.es/b/Articulos-vintage-de-informatica/11189/bn_16553811?rt=nc&_sop=3).
I found 3 interesting items this way: a cute Dreamcast TV (https://www.ebay.es/itm/364536761312?itmmeta=01HV9FXT45KA2Z099KSM4R4AS2&hash=item54e0158be0:g:DDAAAOSw6JRkomdk) called "Divers 2000 CX-1 CRT TV", a rare Korean "Alive 2" 3DO (https://www.ebay.es/itm/314909001119?itmmeta=01HV9FXT45W3A3G2A0CX9VV0DY&hash=item49520a059f:g:4G4AAOSw8SRlNAnX) and a super odd "Wang 600" computer from 1978 (https://www.ebay.es/itm/395037370474?itmmeta=01HV9G076B4FD2XMDERDBKD605&hash=item5bfa0fe86a:g:XFUAAOSwBD5la1z8) whose monitor looks more suited for a calculator (edit: it's actually a calculator according to many websites, but it appears on Ebay as a "computer").
Thanks, that's fun😁
The Korean 3DO is suspiciously similar to the PSX. Since the 3DO was released earlier, I thought I was onto something: did Sony actually steal their PSX design from this?
The truth was quite different: this 3DO was released... in November 1996.
I just learned the Nuon gamepad by Logitech costs almost 400 dollars (https://www.ebay.es/itm/364747782607?itmmeta=01HWNEVPDV5AGF7H55Y99ZMEQV&hash=item54eca979cf:g:ihsAAOSwa1Rl1sJ8&itmprp=enc%3AAQAJAAAA4B6CzJtDPbguSDiqgCvIzS7zGHmgKBIqUAE8%2Biy3ZYrDmkms%2F4Atnoz4O9QXnynOotXuV9yHDmUOi%2F0OvjUs3PqlGZ3hwty9t8BDk7BII5Jy99ZrGC0ZLCkLIIpYDvtxygZw1ZAhVRLWwCGTRdS7NepdRf3hDTvn23058jn3xlLT461rNcXPI9GkXC2tle9iPNM8890U0fc%2BEYfRkWkbciiX4RbCtKjVlcGSjxBuJpStgzPTIXold2P5uR4qT5yIqcI1cWL0YFk2GMmd2Qs30o6l3focCF9kMYiAqdy%2BdT4X%7Ctkp%3ABk9SR_zm7q7lYw).
