Cactus (produced by Harvest-One) is expected to release a new version of their V4 wireless flash trigger by the end of the year (2010). The new version will not be compatible with the current Cactus V4 model.
Cactus is basically a cheap alternative to PocketWizard. You can see a review of the current Cactus 4 flash trigger here.

I hope its TTL. And allows compensation from the commander. Then I’m in.
I meant transmitter, not commander. Also 20m range would be nice.
I don’t care about TTL, but being able to control strobe power from the commander unit would be nice.
I assume one of these years someone is going to realize they have large LCD’s on the back of cameras now and build an RF transmitter into a camera body, and allow us to control matching remote strobes via touch screen. Surely Canikon has had to think of that right? Line of sight system sucks compared to RF.
