Advise on radio triggers for my SB900's

Hi all,

I'm in search of some advise for a solution to my wireless flash photography, my gear and needs are as follows;

I shoot with Nikon D700 with 2 SB900's and currently use the built in flash to trigger my flashes wirelessly (on stands with shoot through umbrellas) which I find isn't always consistant.

I have looked at using a SU-800 to trigger my flashes wirelessly, however I'd like to have radio triggers (most likely Pocketwizards) to guarantee more consistant firing.

What Pocketwizards would I need to trigger the 2 SB900's off camera??

I don't need the most fancy one, just one's that will allow me to adjust exposure manually, or adjust ev compensation using TTL whilst being able to shoot in all lighting conditions as my built in flash won't exceed 1/250..

Any help would be great!!
