Check out YongNuo RF-602 on eeeebay. I have those and they're pretty darn good for the price, they're obviously not as reliable as Pocket wizards. But the misfiring rate is still very low, i think i've only had like 1 or 2 misfires the hundreds of "play" exposures i've taken with it. The build quality is excellent, just as good as the pocket wizards i played with at the store.
Best thing about them is that they can also double up as wireless shutter releases. Win Win for me

The only downside with these vs the Pocket Wizards is that the RF-602s don't support ETTL. But most don't anyway. I prefer to shoot in manual with OCF photography.
Here is a huge discussion of these wireless triggers on PoTN forums.
