Adorama RPS 3-in-1 Wireless Remote Control for Nikon D90 D5000 D7000 Reviews:
RPS 3 in 1 for Nikon D90
I chose the RPS from Adorama for price over the Nikon brand knowing Adorama stands behind all their products. The RPS has adequate range remotely for triggering the camera or from the camera triggering a flash unit. I have not had any problems with it.
