Thanks for all the feedback.
As of yesterday I yet had to convince my girlfriend of buying an used lens with a scratch, since she is at the moment the money maker. Now after reading the new replies I felt like I could be able to convice her by reading the replies, buuuut the lens is sold. So gotta keep the eyes open again.
Anyway, thanks again for all the help, I didn't get the lens but I learned something about scratches
PS: It is really nice to get to read some of your peronal experiences with scratches.
