Looking for alternate non-GW models for Wyrdvane psykers, Ratlings and Ogryns

I am looking alternates for the Wyrdvane psykers, Ratlings and Ogryns and turn to you for help.

Below are listed some preferences for the models:

For all: Either plastic or resin
For all: Grimdark feel to them (i.e no cartoonish or silly etc)
For all: prefered number of different models 3+
Ratlings: No flintlock etc. low tech guns, can be either human sized or the midgets they are in the fluff.
Wyrdvanes: Can be males or females or both. Wear atleast some clothes (so no boobs etc. unless otherwise really fitting models for the role).
Ogryns: Most importantly near the size of the real ogryns. As a reference Warzone Resurrection: Chasseurs would have been perfect if they would have been more appropriate sized.

So, do you fellow wargamers know any that would fit the descriptions, and in general if you do not use GW models, what do you use instead for psykers, ratlings and ogryns?

When Toughest girls in the galaxy comes out they have some amazing models.

Kit-bashed Empire Flagellants from Fantasy have been recommended to me. I've had some luck just cutting down some lousy-looking used catchans and giving them greenstuff robes and staves.

For ogryns you could try these: [url]http://www.manticgames.com/mantic-shop/kings-of-war/ogres/product/ogre-shooters-6-figures.html[/url]
