I am not so lucky, I knew about the err3 problem so checked it was working when I was buying my is200 sport (2000) and it was working fine. 2 weeks later it is broken

(Err3). I have a bottom slot "13902"
After speaking to Lexus engineer he has told me that as mine is 6 yrs old it cannot be replaced for free. Also he says although the newer top slot type would fit in the dash it has different connectors on the back. I asked how much for the "13902" part and he said £1200 (that’s not a typo lol).
So the options I have are
1 get a replacement 13902 second hand - does anyone have one that’s avoided the err3 for sale?
2 get a newer top load unit and do some wiring as the connectors don’t match (Lexus said they would let me have wiring diagrams) - does any one have one of these newer cd players for sale?
3 get an after market unit which will probably look rubbish unless I go for a DVD one with a flip out screen
4 get it repaired, however when I had it out of the dash a small piece of plastic - looks to be part of one of the cd trays fell out so I’m not holding out much hope for the repair. Anyone know roughly how much they would charge?
