What kind of SD map card would I need for a Humminbird 987c SI and where would be a good place to buy one.

Earl,
Are you looking for inland lakes? Your only option is going to be Navionics. The 987 is not compatible with Lakemaster chips.
Check out the Navionics website: http://www.navionics.com/en/marine-lakes-usa (http://www.navionics.com/en/marine-lakes-usa)
