I have a plastic frame press with air pump. I can put my hand on the plates during filtering so it's especially nice with a few young ones running around. I lose very little temperature from fluid going in to fluid coming out. And it's really nice to show visitors the workings of the press as you can see the syrup filling the press and when it's starting to fill up with DE. I had one of the very first models where they had some issues with the molds but Leader stood behind it, gave me brand new plates and all has been good since.
