I use the Pixel Pro flash triggers, they are good value (£45) but suffer from some of the sync issues mentioned above (i think that this tends to be a theme with teh sheaper options?). They are only reliable at 1/160s (rated @ 1/250s)

I use mine on a Nikon/Nissin combo but I have a friend who uses a similar set up that you are describing.
Hope this helps, Gary
