I didn't see it, but how about a nice flash. You wouldn't be able to get a very good P-TTL flash for $200 (at least not a powerful one that isn't discontinued, I don't think), but I have been using 2x Yongnuo YN560 II all-manual flashes, and I must say - they are amazing. $60 each, so even if you get just one, that leaves you enough left over for a cheap light stand, softbox/umbrella (or both), and radio triggers (I use the Cactus v5 and I find them incredibly reliable, but there are some slightly cheaper models out there).
And then you can head on over to
Strobist and read his excellent
Lighting 101/102 course (which is free!) and experiment with off-camera flash.
