Inselburg has none. I have gotten 14 from the Portland castle, and checking the shops in the same area, saw 15 more. So that's a grand total of 29. I think I saw some more on Sandy, but I also found a lot of Archies and Trolls there, so I will be ok for the time being. The shamans shine in a level 5 setup, and Demonologists + Phantom can res level 5 units easily.
Eventually, I would love to get more Dark Paladins, though, cause I want to use them is a similar setup as yours. I kind of envision my late game with Dark Paladins, Knights or Dark Knights, Executioners, Demons and Demonologists. Level 5 units become a pain to resurrect after a certain level, as the enemies grow quite powerful, so level 4 army, as in KBAP, looks like the way to go.
