Recently we have succeeded in growing a series of high-quality Bi_{ 2}Sr_{ 2-x}La_{ x}CuO_{ 6} crystals in a wide range of carrier concentrations. The data of \rho_{ ab}(T) and R_H(T) of those crystals show behaviors that are considered to be "canonical" to the cuprates. The optimum zero-resistance T_c has been raised to as high as 38 K, which is almost equal to the optimum T_c of La_{ 2-x}Sr_{ x}CuO_{ 4}.
