I feel like this is one of those sellers where it might almost be better to ask about items on an individual basis, as I suspect he gets things from a few different types of sources. My instinct is that his inventory is generally good. He has a couple of U2 (Bono) items that might be fine but aren't particularly good examples if they are and certainly not worth nearly the prices he's asking. Seeing other items I'm familiar with that look just fine though.
I agree with your opinion.
