Which remote trigger is good for my Nikon D90 and SB800?

Can someone recommend me a decent remote trigger? I have a Nikon D90 and SB800 flash.

Depends if you want to maintain TTL (fully auto) flash metering, if you do then your limited to either a dedicated lead or the even more expensive 'Radio Popper' (about £300.00)

If your happy with manual everything then things get a lot cheaper. The Yongnuo RF-602 (less than £30.00 for a transmitter/ receiver pair) such as this one will do the job reliably.

Be sure to get the Nikon version.

Check out this site which is all about using cheap manual flash off camera.

Look in the 101 Archive for everything you need to know.

Here is a video that talks about a lot of cool things you can do.

In it, there's mention of how to use a Pocket Wizard to set off your camera remotely. The on-board flash can trigger the SB800

I think you should go with Satechi TR-M Timer Remote Control for Nikon D90
