Ugh, that price gouge is revolting.
It looks like the Monster Manual and DMG are available at reasonable, if not very discounted, prices. Just the Player's Handbook is being marked way up.
If you're looking for a 3.5 PHB though, there's at least one for $18:

The Player's Kit has, among other things, a softcover version of the 3.5 PHB. It's the whole book, full sized, just in softcover. I have it and actually prefer it over the hardcover.
