You could also add the prices of torch bug paste from Complete Scoundral and eggshell grenades from Oriental Adventures, then multiply it by 1.5.

I kind of like that hyper-localized take on it.
Out of curiosity, what will you rule if the attack misses the target?

Yeah - since I believe the point of gliterdust is to help find someone who is invisible. Why would you limit it to "target" unless the target was a single 5 ft square.
