I tend to run my own campaigns over prewritten stuff, so I'd like to know before I go out and buy any of the prewritten DH books, do they contain any awesome equipment or enemies that make them worth getting as source books?

Thanks

Purge the Unclean contains stats for some Dark Eldar and Dark Eldar weaponry among other things.

Tattered Fates contains a good deal of info on the pleasure world Quaddis as well as a special elite advance (although the elite advance is only eligible for player characters who have completed the scenario).

So while not sourcebooks in their own right, they do contain info that you won't find in other sourcebooks.

Same as what Varnias said...

...plus they are written in an open way. Adventures 1 & 3 of Purge the Unclean are great as mini info books for the nobility of Sibellus & for the mines of Sepheris Secundus.

Tattered fates is written so open it's more of a "sourcebook" than module IMHO.

My suggestion is go down your local gamestore and have a quick read there before you decide. (I will say I'm biased and I love any written stuff even if I'm not goin to run it...)

PtU also contains a blessed Power Sword, and has quick-and-dirty Space Marine stats.

Tattered Fates contains base stats for typical citzens of Quaddis as well as "Killers" amoung them, with a number of templates which can be added on to each. These may be useful as an alternative to, or in conjunction with, the various basic stats for human NPCs in the core book.

If only for additional fluff and world details all of the books are very much worth it, even if you never run the adventures in them. FF is really doing an outstanding job of adding detail to a already rich universe setting.

The best that can be said about Tattered Fates is that it provides good info on the world of Quaddis.

The rest of the stuff is poorly presented, the language overly flowery, and there are too many 'you can fill in you own stuff here ' because we didn't bother.
