Thanks to David for reminding me about Yongnuo's new RF603 Wireless Flash Triggers. The new RF603 version (replacing RF602) is both a transmitter and a receiver hence the name 'transceiver', so you can use each one as both. The old RF602 version required both a separate transmitter and reciever unit in order to work. There's a few more new features that make the RF603's a better buy if you don't already own a set, but a bit of bad news is that they are 'not' compatible with the older RF602's. Blah. I have quite a few of the RF602's.
One thing that might be confusing if you're looking at the product pages would be the difference between Canon and Nikon versions. The units are all the same and the difference is the provided shutter cable. The RF603 Transceivers can also act as a remote and receiver to fire your Camera's shutter wirelessly (sorry no video starting). You can find out more information about Yongnuo's RF603 following the link.

Yongnuo’s RF603 Transceiver Wireless Trigger sets really seem cost effective valuef for money.

I ordered a kit to be used with my same brand flashes. But in this case im dissapointed. They never worked and because are a chip product is relatively expensive to return them, so was a waste of money. The Yongnuo web dosn't have a troubleshooting page or support, so there is no aftermarket service. And also have two design failures: It has not lock to secure the transmiter to the camera hotshoe, and once installes a flash unit you can't reach the power switch.

Post author@Anthony - I'm using the RF602's and they've been great for a long long time.

I know this is old, but anyone have any experience with these? Would you recommend it?

My RF-603c came in. I have a 5Dmk2 and a YN468 Speedlight. I noticed having the camera set to "live view" causes problems with Transceivers- Lucky to get a photo and wireless flash at the same time. Take the camera off "live view", and the wireless triggers work perfectly every time. Any one else encounter this?

uhm. I thought all these TTL triggers were only passthrough, not to the other flashes. talking about the cheapies not the pocketwizards.

@ Emm,
Yeah no HSS 🙁 , But with the way these small companies are pushing out items so fast who knows what 2011 holds for us?!?!

I use Pocket Wizard TT1 & TT5, I'm looking another cheap brand for backup, the new RF603 seem like a good option.
Here is another option no yet on sale but with TTL: https://www.pixelhk.com/Proshow.aspx?id=101

Post author@ Serge - Those TTL ones look pretty cool, too bad they don't support HSS. That's the great thing about having communications between the triggers and cameras. Good find.
Serge
Well I been seeing some of the other cheaper brands start implementing TTL and ITTL...

Im with Rico since you have so many if you want to get rid of a set please cut me a deal 😉
Kevin
Really a shame it does not work with the existing 602 model. I have a ton of these and would love to re-use them.
Emm
Post author@Serge - None of these have TTL, even some high end expensive Pocket Wizards don't support TTL. For firing in a studio, no HSS, or shooting Manual Flash it's not necessary.
Emm
Post author@Riko Gonzalez - Sounds like a plan!

Apart from the Tranceiver desing I dont see much of a Difference to the 602's, But Emm if you get them 603, be sure to sell me your 602's!!! 😀
Serge
No TTL???
