Yes, a Radio Shack multimeter should do fine, but if you want something better you might consider Triplett, which has been around forever and makes both analog and digital meters which are widely used by electricians, electronic technicians, and engineers:

Also, Simpson was for many decades the leading name in high quality multimeters, although I have no knowledge of their recent products or ownership:
