I've been on the WEISS course. It's tough, challengeing but very rewarding. I'm not going to give you a review and no one will as it will give the game away. But it is well put put together by Preben, Gary and JP. Well worth doing.

Your best bet is to email Gary at Bearclaw Bushcraft. Some experience is needed and you do need to be in good working order Go for it, you will not regret it I can promise you that much.
Price: starting from 112 €/person/day for the Rundumpaket.
I have looked up the word that didnt translate via google in this line:
Rundumpaket = 'The whole package"
probably best to ring or E-mail Preben via the details on his website and ask for more information
The WEISS course that you are looking at on Preben's site is a 10 day course, the one we have just done covers everything that one does but is compacted into 7 very hard and tiring days in order that students don't have to take too much time off work, this is why the prices are different.
Also, not all of Preben's instructors do speak english and I can tell you from personal experience that not all the locals or hospital staff do either, if you wish to do the non-Bearclaw one then you'd better make sure you speak either Swedish or German pretty well.
I doubt very mich that anyone from bearclaw just stands around counting money for the week... I suspect very much that they add value to the experience and provide useful insight in carrying the knowledge from Sweden to the UK... As an example: As good as he might be, I doubt Preben knows a thing about which plants found in Sweden might be found over here.
