Those are all some nice looking setups.
Here's mine that I just put together. It's in the corner of my sunroom and the total cost was less than $200 for the 2 cabinets. Everything else I had left over from my kitchen remodel or laying around the house.
The center section has a piece of countertop that drops in place if I remove the press, so I have a nice 90" long counter to work on other projects if I'm not reloading.
I'm going to get a fire rated safe to put between the cabinets that I'll bolt to the concrete and wall. That'll be were I store my handguns, powder and primer.
