Kinda tangentially related, but I am having a good time building this kit currently

Don't really need them, but fun. Really nice components from PE given the price. Though I am already in for another 150 on stands, 50 on paint, filler, sand paper etc. Not to mention probably 20hrs of labor so far. I cant wait to hear how they turn out.
