i use the shen hao 6x12.
had some troubles at start see (http://www.foto-art.nl/articles/shenhao/holder.htm) but after that it worked fine.
Be aware that you will have to look into the red dot to move the film to the next spot. This can be a bit tricky with low light (little torch).
Film is laying flat, on my site i have several 6x12 images posted. I like the format very much, i use a lot of slides with it.
Email me if you have specific questions.
I have been using a Shen Hao 612 with very good results. Bought from UK supplier Foto-Arte in London with warranty and all duty/vat paid. I didnt think the difference in cost warranted the potential downside.
Hope that helps.
