If Malifaux has to be your secondary hobby, Ressurectionists are probably not the best faction to choose, because picking up master with many summoning options (Nicodem, Molly, Kirai) will result in buying tons of models you will never field but summon in the course of the game. Well, in fact even playing masters with limited options it may happen that you buy and buy ad infinitum (e.g. you play Seamus, who synergises well with Datsue Ba, so you buy her, but she summons Gaki, so you buy them, and rarely she summons Onryo, so you buy Kirai's box, and then you have another master who summons spirits, so you start to buy them).
