Walt, I can not remember what I paid at the time, but got them from the guy listed
here. Great seller on ebay, and he combined shipping on my light meter. My camera trigger cable also came from ebay in as new condition from a person who dropped Nikon and went back to Canon, so I got it for under $80. The trigger cables are usually in the $120 range. There are cheaper ones but I was worried about functionality with an expensive camera.
I will add the range on the Plus II's is incredible. They have never failed to fire. Mostly I use them to trigger my camera more than using them to control a remote flash. Damn Nikon not offering a remote for their D200's.
One of the coolest things to me, that I have seen done with the PW's is photographing Hummingbirds. Their wings move so fast, and with the flash hitting them just right their magnificent colors come out.
Edit: Walt if you want three of them, I would take another one from a two pack. It would help me get away from using my SB800 in remote mode. I have a really old Olympus flash that I currently use with my PW.
