I'm sure that I have seen some attempts to assign DH costs to RT weapons.
I tried to search forums, but haven't found such topics. If someone have any info about such conversions - please let me know (maybe someone use such equipment in their games)
The Adept I play has an Arms Coffer. We just came up with prices on a case by case basis. My "basic" arms coffer cost me 100 thrones as I recall; this included a pretty basic gene-coded lock.

Over on the RT forums I posted this:
Here is a system I came up with after reading this thread. I'm not going to argue over whether it should have existed or not but:
You can create a very generic and generalised cost system using the availability of items:
Avail Cost (tg)
Dark Heresy Availability levels

These should all be GM discretion only. If legitimately buying something with this availability the GM should modify it as much as they deem appropriate.
Extremely Rare - 100,000+1D10x100
Near Unique - 1,000,000+1D10x1000
Unique - 100,000,000+1D10x10,000
Modifiers:
Bolt: Add 1D10x10
Plasma: Add 1D5x1000
Melta: Add 1D5x1000
Xenos: Add 1D10x1000
Power wpn: Add 1D5x1000
Power armour: Add 1D10x1000
Primitive: 1/2 cost
Pistol: Add 1D10x10
Heavy: Add 1D10x100
I'm sure you could go into more detail and this won't represent everything perfectly. Obviously if a similar weapon already exists it shouldn't cost too much more or less than that.
The thing to remember is to look at the availability and compare it to an already priced object of the same type. If you are looking at the availability of a Plasma Pistol (Ryza) (Very Rare) and compare it to the cost of the very rare plasma pistol from the DH book, then it shouldn't have too much of a cost difference, it would cost more though because it's better.
You could simply look at the item's stats and availability, find a similar one with the same availability and then reduce or increase the cost relative to its quality (ie if it is worse reduce the cost by X, if it is better increase the cost by Y).
This isn't a substitute for proper costs, but the availability should give your a very rough idea of how expensive the object should cost.
It might provide some general guidelines to help but I make no claim that it will immitate every cost in the DH system perfectly.
