I absolutely love the Cybersyncs. I am in fact today I'm using them to do a portfolio-building photoshoot with a really gorgeous young lady.

Anyway, I chose NOT to get the PocketWizards because I think they are overpriced and more bulky than the Cybersyncs. The Cybersyncs are very well built, made in the USA by a small company with amazing customer service, and they fire the strobes every time. Very very reliable.
The new PocketWizard Flex TT5s are neat, but their operation is supposedly interfered by RF noise emitted by Canon 430EX and 580EX, limiting the range to 30 feet.
The Elinchrom Skyports were my second choice, but they do NOT have removable AA batteries like the Cybersyncs and PocketWizards do. This could be an issue when you run out of batteries during a photoshoot. The Skyports unfortunately use a proprietary rechargeable battery that remains inside the enclosure - you just plug them in to charge like a phone. This could be a convenient feature but also ruin your photoshoot.
Price comparison between the 3 most popular wireless flash triggers assuming you want to buy 1 transmitter and 2 receivers:
PocketWizard Plus II (Transmitter/Receiver combined) x 3 = $507
Elinchrom EL Skyports Transmitter, 2 Receivers = $267
Paul C. Buff Cybersync Transmitter, 2 Receivers = $240
On a final note, I would highly recommend staying away from the Hong Kong eBay triggers like the Cactus V2s, or the other eBay triggers known as Poverty Wizards. They SUCK! They fire only 80-90% of the time, drain the expensive CR2 3-volt batteries, and are very poorly built. I made a battery mod to them to allow the use of AA rechargeable batteries, which significantly improved their strobe fire reliability, but they still sucked. Here's a photo of what mine looked like before I sold them for $50... ghetto...LOL:
