Best mini series for player character types?

[bujoojoo]

Which would be the best line to acquire minis for PC and NPCs? I'm looking to expand my (meager) collection for my upcoming campaign. Also, what about hirelings/pets? The Reign of Winter line looks promising for animals/familiars, any other suggestions?

thanks!

Consider the Pawn box sets if you want big expansion on a budget.
