Magazines for the Rolleivision 66 Dual-P

Does anyone know where (worldwide) I can find the Rollei CM 77/30 interconnectable magazines or similar, for the Rolleivision 66 Dual-P slide projector?

My current supplier stopped selling them, so I'm desperate to find a new source!

I want magazines that go directly into the projector. There exists slide storage boxes with which it's necessary to shift all the slides over to a real magazine for viewing in the projector. This is not what I'm looking for.

Any ideas would be greatly appreciated!

Is this what you're looking for? They work in my 66.

I think the ones I've been using have cost around $30 for a box of two 30-slide trays. So the ones at B&H seem rather expensive..
