Hello, I recently got my hands on Rogue Trader and Deathwatch and want to bring some of the items and NPC's in the books into my Dark Heresy campaign. However I am having some problems coming up with price points for most of the items. Does anyone here have any advice or house-rule I can use to bring these items into the game?

Most of that stuff is roughly around the level PC's would be using Influence and Acquisition for anyway. If they're pre-throne agents you could always bring in the DH influence system in slightly earlier, I did, bean counting annoys me.

Which items do the players want that would be appropriate for your acolytes to have ?

If you narrow the list down a bit, I'll try to work out some prices for the RT items. How willing are your players to take the five finger discount ?

For Deathwatch items, they will need to steal them from someone. The fun with them will be figuring out how it injuries any acolyte who tries to use it.
