The ideal indomitus models are the hero series, if you have access to a decent recaster.
They are slightly bigger than the classic indomitus models, their poses are far more dynamic/interesting, but they're not oversized 40k slop.
Also in case you're wondering, although almost no pictures ever show it, they do all have the option for helmets instead of bare heads.
