If I had a mildly stable income, I'd probably pick up Kira Kira. I've read it before, it's decently priced, and it wasn't just released after a perfectly good fantl was out (saya no uta is really cheap though, apparently). Otherwise, maybe Higurashi if I get to reading it, 999 (I don't actually own a DS, so it feels a bit strange but still...), and yes, the PW games.
