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.
