LAX to NANOG 35 - bus/shuttle recommendations?

The Hilton website is suggesting a $13 far for bus service from LAX to NANOG 35 and $50 for taxi. Any recommendations on where to find said bus service, and if reservations are necessary?

See you in St. Loui^H^HLA!


Supershuttle is best ( - $16 each way. And Burbank airport is much closer, if you have the option.
