You will not find anything for the last 4 minis.
I have not seen a mini sell for arms since the price skyrocket.
But how it always has been: Back in the days when Zippys were 300a (undead) we had the IG/Pandas in ded at arround 1300a.
Even later the prices stayed arround the ratio of ded panda/IG = 4x undead zippy in value.
unded is probably 2x ded IG/panda.
kanaxai is something like 2-3x unded IG/panda.
