Upkeep for summoned units

I don't know of any non-recruitable units that cost upkeep.

From Dominions_2 the summons I remember which cost upkeep were:
1: Sea Trolls... about 3 gold per turn
2: hawks from "call of the winds" ... about 0.25 gold per turn
3: foul spawns from "cross breeding" spells... about 0.30 gold per turn


These amounts may not be 100% accurate, but they are close and these amounts may have changed with Dominions_3.
