In order of when I'm likely to buy them...
YAY - wireless trigger set (the $25 kind, but I was still excited)
YAY - a donation! 50mm f/1.8 lens, 75-200mm f/3.8 telephoto, and flash unit. "Series E"--a generation old, no electronics--but I was still excited.
~$1000 upgrade camera to one that supports bracketing, high speed synch, and better lenses. (My Nikon D60 is constrained to DX-series lenses, which aren't usable on any better camera body.) D300 would be my choice from the Nikon line.
$50-100 boom light stand, umbrella, and umbrella swivel
