Has Hulk 181 Peaked?

eBay item 2246896690 (Ends May-28-04 17:30:00 PDT) - INCREDIBLE HULK #181 CGC WHITE PAGES

Here's a nice clean CGC 6.0 Hulk 181 with a $500 Buy It Now that's been untouched for over a day. Seems to me that this would have been scooped up in an instant at one point. Given the insane prices for VF or better grades, I'd think a copy like this would draw some attention. Is the Hulk 181 fever subsiding? Or is demand for mid-grade books lower than I thought?
