Thank you all for your replies. It will help me with my purchase. Now I have to unsubscribe again, caus my woman thinks this (very enjoyable) mailing list costs me too much time (time she wants me to spend with her).
So I'll see you guys later another time. And oh... I could of course go for the 'no mail' option... I've heard about it... Could anyone tell me how to do that? And Mark, I'll try to get in touch with someone from my old college (electrotechnics) to check if someone can identify the codes. Take care y'all.
