These are always the best bang for your buck! Highly recommend getting them if you can!
I lucked into getting a couple molds that I had been questioning buying anyhow, and got some great plastic (1 in 400, 2 in 500, 1 in 750, 1 350).
X3, Dickerson FX2, M4, KJUSA A2, Paju PA1
I would definitely buy again (even though I really shouldn’t)
