SanDisk Ultra 16GB SDHC Class 10 UHS-I SDSDU-016G-U46 (Personal Computers)
This card is excellent with an SLR, Nikon D90 in this case; fast, reliable, good capacity (More than 1,000 shots in RAW on a 16 GB) Only downside, it is delivered without its small storage box :-( Which cost him a star less! ;-)
