Campy 10 speed rear derailleur question

I broke my 10 speed Ultra -Shift Centaur rear derailleur today riding on a very muddy trail. The trail was submurged under water for a couple of days after the hurricane and I thought it was dry enough
I m wondering what my options are of replacing it.
Apears there are some used Centaur medium cage mechs for $100-$150 on e-bay.
Also looks like Campy makes a new 10 speed Veloce rear mech with new improoved technology, I think it is for Power-Shift. Im not sure.
Does anyone know if an 11 speed Campy medium cage works with 10 speed Ultra Shift shifters/cassette?
I would like to have a bigger capacity rear derrailleur if possible since I m running a 12-32 rear cassette (48/34 chainrings in front). That is the reason I m concidering an 11 speed rear derailleur.
Any advise is apreciated.

11sp RD won’t work with an otherwise 10sp drivetrain. Find a medium- or long cage 10sp RD on eBay.

I think the Centaur RD13-CEBX3 will handle your 32 in 10s Ultra.

Nope. I have an 11s Athena on my 10s Veloce groupset and it works like a swiss watch

edit: cheeck your derailleur hanger , probably you must replace it as well , judging by how the derailleur itself.
