Does anyone know of a good source of free or inexpensive high quality photoshop layer styles?

The key phrase here is "high quality" ... googling turns up lots of sites where you can download random style sets but basically I can make crappy styles myself so they're not helpful.

I used to have a copy of the Photoshop 7 WOW book that came with a CD that had a fantastic collection of glass, plastic, glossy metal, and brushed metal styles -- unfortunately I lost that CD years ago, but what I'm looking for is something like that.

I am also looking for the same thing - HQ layer styles. I've spent a good amount of time searching around, and there are some decent free ones, but I feel like there has to be more out there...
