We report that it is possible to obtain a series of high-quality crystals of Bi2Sr2-xLaxCuO6, of which the transport properties have been believed to be "dirtier" than those of other cuprates. In our crystals, the normal-state transport properties display behaviors which are in good accord with other cuprates; for example, in the underdoped region the in-plane resistivity rho(ab) shows the pseudogap feature and in the overdoped region the T dependence of rho(ab) changes to T-n with n > 1. The characteristic temperatures of the pseudogap deduced from the resistivity and the Hall coefficient data are presented.
