Durst DA-900 - negative carrier advice please

I am considering making a bid for a DA-900 with CLS-450 light box. It is described as fully working, comes with 50mm and 80mm lenses, and a DUONEG carrier for 35mm and 6x6.

I would also like to be able to enlarge 6x9 negatives. For this I understand I will have to obtain an AUTONEG carrier. Please can someone confirm if this is correct? How easily available are these carriers?

Thank you
Ian

I have had a search on UK and US eBay, but can't find one, unless I have the name wrong.
