I've been playing with coating my own plates and have run into some serious issues with the holders. The old, wood holders I bought simply, SUCK. I mean they don't work worth a damn. Even though I get 2mm glass, I can only load one plate at a time. So one side is unused. And then they often warp with the plate in them so just getting the darkslide out is a nightmare. I even lost one today because the holder warped so much that it buckled around the plate! I am going nuts trying to solve the holder problem! I am thinking about getting some Linhof "Universals", but they seem few and VERY far between (I found one for, no kidding $200!) I am at wits end here. RIght now I have a couple of Ansco "Dry Plate Holders" and one Premo holder (which doesn't really work because the darkslides are too short to be usable). I am DESPERATE to get something that will actually WORK. Does ANYONE have a good source for plate holders at all? Or even some Linhofs they would be willing to sell at a reasonable price (I mean $200.00....for ONE! What was that about?)?
