Anyone Know of a C.C. Lemon Equivalent?

I love Suntory’s C.C. Lemon soft drink, but around my area, a 12 ounce can costs $2.95. Can anyone suggest a widely available American beverage with a comparable taste? I’m already familiar with Sprite, Fresca, Sierra Mist, and Surge that are vaguely similar but really don’t have the same taste as C.C. Lemon.
