You're on Colin. Thanks.
From one who has known only modified holders, I'm really enjoying a dedicated holder. Modifieds are fine, don't get me wrong. I'm just finding it a lot easier. It even seems I am getting better plates due to less fiddling with 2 slides, loose, pressure springs, etc. I also find with modified holders that they are less substantial and easier to mistakenly compress the plate up against the darkslide and perhaps that is why my plates are cleaner.
Looking forward to seeing the camera! It'll be good to have another for the workshop.
