I've updated the thread at the top will all the latest info... even if it's not as neatly presented as I would like (I'll keep working on it

)
We have quite a lot which currently have not been found in the USA or are two expensive in the USA, as well as a few with similar problems in Europe. I've been doing some searching and found more information on some and I will carry on doing that, but if anyone else comes up with a good (and cheap enough) supplier for any of them then please post it.
Thanks everyone with the help so far.
