Cheap airfare from indianapolis, IN to Seoul, South Korea?

hi, i'm looking to go to Korea from either july 28 or 29th to August 9 or 10th. Can you recommend me the best site with the cheapest airfiar? I have found one that is $1230 with tax and i'm trying to find one cheaper. I would prefer the minimum stops but if the price is lower than 1230, i would take it. It is roundtrip, coach seat and that's pretty much it. Thanks
