There was a time, not too long ago, when it was easy to justify picking up any Underworlds warband that took your whim.
Sure I don't need the cards and models, but I would really like to practise painting yellow. The Ironjawz warband it is! After all, they're only £15...
But looking at The Exiled Dead, it's £26 for 6 basic zombies and the vaguely necromancer-Vampire. A few more quid and I can pick up a whole AoS unit... or hell, £9 more for 20 Zombies. It was only a couple of years ago that buying the Kharadron warband for the Aether-Khemist was actually cheaper than buying the standalone AoS model.
It's no wonder that Underworlds has rapidly started drying up around me with the new price hikes, when it was with Beastgrave that the game was really picking up momentum as the fast-and-cheap option for people who wanted something a bit more competitive without splashing out for a whole army. It was also cheap enough that people were less wary of spending money on a non-40k/AoS game that might go into cardiac arrest at any moment the way most people are with other games.
Just a rant.
