sometimes cheapo air will have stuff as well as kayak.

I work at a travel agency that does international travel and i have noticed that sometimes getting a round trip, even though you only need one way, will be cheaper and just dont use the other half of the ticket. $200 doesn't seem TOO bad though. I got round trip to San Diego back in Feb for about $300 out of Chattanooga. Also, traveling during the time of year that you are is going to cost more anyway since its during the summer time.
