Aside from Dark Angels (ten Deathwing Terminators plus Land Raider = £115, and you can bet they won't be Troops for long), Black Templars (ten Initiates plus ten Neophytes plus Land Raider Crusader = £101) and now maxed-out Kataphrons, is there any Troops choice that actually costs more than £100? Even twenty Sisters only come to £80ish, and they're metal. (I suppose you could push it over by adding a transport they can't fit into).
