Is this fair?

MY mint duncan momentum for someone’s protostar,dingo(One Drop) and a grind machine two?

is the grind machine 2 metal, or plastic? if plastic, then It’s a very fair trade.

if both parties agree to a trade, then it’s fair.

i think so. the momentum is around $100 new
the protostar is probably worth around $25 slightly used
the dingo is probably worth about $40-$45 slightly used
if its the pgm, then its an even trade. if its the metal gm2, then its worth around $80 i think, so you just got an amazingly good deal!
