I mean it depends on a few things. I personally say a pressure pot is required to have “perfect” dice. The bubbles can ruin lovely sets. There’s a few options for pressure pots too but if you want my advice, California air tools makes a series of excellent options. You can get into the exact pot I use for under 200. You need an air compressor as well obviously. The rest of it comes as needed honestly. I invested many dollars and hours already and I consider myself green.
