Are any of these books worth grading?

[Zanarkand]

This may be better off in a different thread, but... How much leeway do you guys give on an ebay seller in terms of grade? For example, what would a NM, VF, or F need to come back as (at least in your opinion) before getting annoyed?

 

I assume anything I'm looking at is a full point lower than stated and bid accordingly. This is of course assuming that they have a halfway decent pic.

 

Anything (other than Modern) claimed to be above NM I don't believe, period, and bid accordingly.

 

I usually don't get annoyed unless the book has undiscolsed interior defects. Often symptomatic of simple grading laziness and it bugs me.

 

I don't have very deep pockets and I rarely even spend as much as $100 on a book, so I'm never out much anyway.
