It wasn't hard to find a mini for my Sister of Battle in our Dark Heresy campaign. There are plenty of Sisters available. But for my Rogue Trader? Absolutely nothing. There is a notable lack of any decent female models for WH40K, let alone a female Rogue Trader captain. Or even a former Imperial Navy petty officer.
I spent several hours browsing through the online catalogs of other model collections. Ended up going with a Freebooter model. It would've been nice to have the option of buying a WH40K model, though. Games Workshop needs to get on that.
