The thing about P1 pieces once they arrive at your doorstep the size and box size will sober you up about space. I'm about at the cap with having 3 already and 2 on PO. Can't do too much more than another 1 or 2 in 1:3 scales.
Yep that's why Ive gotten rid of almost everything else in my collection and have reorganized to make room. Totally worth it.
