Oh-man-oh-man, not another newbie. J/K.
To answer your questions on Yamato products, you came to the right place. I have the MPCs and the yamato 1/48s, 1/60s etc. Yamato toys are far superior than Toynami. I can attest to it. I am a big Max fan and needless to say I have 8 of 1/48 VF-1J Max with the fast packs. Yamato toys are worth the money.
You can order thru Twin Moons or Valk Exchange though the Max are getting scarce. The VF-1S are being re-issued for a 3rd time. The VF-1S are from the Macross Movie Do You Remember Love which is the VF-1S is white note grey like the TV version.
