Can any one recomend a small flash unit?
METZ 44 AF-1 Digital good size and I think would tick your box's
Lots of manual flashguns but one of the better ones is made by Lumopro although may be a little large? Anyway you get a lot of bang for your buck. take a look at http://www.lumopro.com/

But i don't think that's the flash you're looking for though.
It must be one of the lower Metz or Pentax flashes, those are small and do what you want, just give more flash power.

TTL mode won't work, but you'll get Program Flash if you set the flash to one of the two auto modes and the camera to P. This flash also has variable power in manual mode and takes up very little space.
Bonus: It'll work fully with all the other bodies in your sig!

My search also turned up the Metz 24AF1, but is seems to be only pTTL with no manual controls. Also the Metz 20 c2 auto/manual flash. Does anyone have any experiance with these two flashes on a K10/20/7 or 5?

Depends on how fast you want it really, but if you're prepared to wait and watch for a while you can usually find things cheaper.

It will also need to have a manual seting so that I can select lower power for manual off camera flash using wireless triggers.
