OK, thanks for the information...
Saying how much something is worth is always hard to do... I can't guarantee you that the prices I give you are the correct prices for the product...
But this is what I think about it:
EAS 7606 = €40 - €80
ES 7604 = €60 - €90
If someone knows a better price, please post it in this thread...
I'm not responsable for it if the price is too high or too low.
I really hope this helped you out,
Josed.
