My observation is that a lot of people are making silly money with vested
interests in the field of EEG.

Just wander over to www.farnell.com . They supply next day in Germany.

I also found no difference between tin electrodes and silver.

"hoch flexibel" just means that it is very flexible.

Such wire is good for electrodes in frequent use in that it doesn't break as
often and bends easily.
