$$ value of Party Poker Points?

[JackOfSpeed]

How much are these things worth, roughly?

I ask because my a*hole of a brother entered a freeroll without asking me that used up 1000 of my points. Was wondering how much he's going to have to pay me back - I guess I could calculate it by seeing how much the freeroll entry was worth in EV, or how much PP stuff the 1000 points would buy from the PP "store," but I'm too lazy.
