Recommend a wireless ttl flash trigger for Metz af48/af40 for Nikon?

Hi there

Can anyone recommend a wireless trigger that has ttl function that can be used with a Metz AF 48 or AF 50 flashgun for Nikon? Anyone know of any that are compatible other than pocketwizard?

Thanks

I use Radiopopper, love it to death.

Radiopoppers do look good although not sure of their compatibility!

Pocket Wizard are'nt compat with them and nor are phottix, only ones I've seen that are, are the Pixel King Pro. They're in the range of cheaper triggers but the reviews seem pretty good for them on the whole.
