Don't even consider 1x4's for this. 2x4's on 16" centers is the method that
will be most successful. You could install them with metal brackets if you
don't like accurate cutting and nailing but if you get set up properly it
should not be a difficult job to just cut and nail.
Don't forget to check the evenness of the existing joists. If they are not
reasonably straight and even (level is not very important) you would want to
use a guide string and shims as needed.
