I believe Adorama has a deal on Sandisks right now. 64 gb 90mb/sec Extreme card for $21

16 is plenty until it's not. On a 16gig card I can only shoot like 250 photos with my d800.

/nevermind - get the 32gb Sandisk from Amazon for $11 or whatever. https://www.amazon.com/gp/product/B013CP3KZ6/ref=s9_nps_hd_bw_bCu3e7X_g147_i5?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-11&pf_rd_r=HNCX31N30513516J9NK8&pf_rd_t=101&pf_rd_p=a918920c-1e44-57ef-b6f3-a1d02a626925&pf_rd_i=11821938011
