We booked Speedi Shuttle with our reservation and the cost is $19.12/person each way (shared shuttle). For us it would have been $152.96/RT (2 adults, 2 children) but when we booked our reservation, there was a promotion so we didn't pay anything. Charley's Taxi sounds more cost effective but make certain you book a taxi in advance. My friend didn't book a shuttle or taxi ahead of time and her flight came in late and there weren't any taxis available. Luckily Speedi Shuttle was able to get her family on one of their shuttles at the last minute.
