Asia - Busan "limousine buses"

Hello, I will be traveling from the Busan (South Korea) airport to the Daegu city center soon and have read that "limousine buses" are a good option; however, I have not been able to find any more specific information. Could someone please suggest some company names I could search for (websites?) to check out for planning purposes: i.e. location info', schedules, cost etc. The most useful information I have found so far is at URL: http://www.airport.co.kr/doc/gimhae_eng/info/RE03010101.jsp but I was hoping for some more detailed information. Thank you for your help.

AFAIK, They are just regular buses that take you from the airport to wherever (usually have preset routes that stop at certain destinations). you just find your bus, and get on it. They just call it limousine buses, but its nothing limo like (maybe foot rests), but in general, they are just buses. I have never been to the Busan Airport, but if it is like ICN, you just go to the bus stop, wait for the bus, and get on it.
