Look at (if you can still find it) Mid-War monster in the flames of war range, it can certainly spice up a "normal game" Those KV5 are BRUTAL on the table top.
I've never owned a paint booth and have yet to find it a necessity for me personally.I spray acrylics at very low pressure right in my hobby room and never have had anyone in the house complain about it.Enamels would cause a problem for sure but I stop using them years ago.
