  We argue that the lightest isospin 1/2 partners of the Z^+(1530) s(bar)uudd
penta-quark predicted by Diakonov, Petrov and Polyakov are not the N(1710)
mixed anti-decuplet states, but the pure non-strange u(bar)(ud)(ud) and
d(bar)(ud)(ud) penta-quark states which may lie as low as 1200 MeV. The
expected low width of a few MeV of such a putative state may explain why it was
missed in phase shift analyzes of pion-nucleon scattering.
