750$
Transcendant C'tan x2 unpainted
Obelisk/Vault (Lord of War) 1 unpainted
100$
Total: 850
All but about three things are painted. There's also about 10 or so unpainted unassembled warriors not included in the count. One deathmark needs a new head and one warrior needs a gun (someone threw dice at my toys). I'll repair those, I can paint the C'tans and Lord of war to match later.
I won't break it up cause its a complete army. I will sell the vault and a single Transcendent C'tan for 100.
