Exchanging Currency Before LAX or at the Airport?

Hey everyone,

Heading out on a trip soon and I'm trying to figure out the best way to get some local currency before I land. Should I exchange some money before I get to LAX or wait and do it at the airport? I've heard the  LAX airport currency exchange rates aren't great, but the convenience of having some cash on hand right away is tempting.

Anyone have experience with exchanging currency at LAX? How were the rates? Are there any better options outside the airport?

Thanks!
