Per Leigh's question in post #16, all the brands of film holders work well, and none need to be avoided... except the flimsy Mido and Mido II holders. (And there are people who will speak up for them, too.) Remember that none of these devices were designed as craptastic consumer "goods", rather they were professional tools built to last. Witness those wooden Graphic holders, some approaching 100 years old and still doing the job. There was an article in 'View Camera' magazine, c.1992 or 1996? that detailed a comparison test of the various holders... can't remember the results though. IIRC the Grafmatics held film the flattest, but anyone who is interested should track the article down.
