The Pocket wizard PLUS X was just released not to long ago. The PLUS X has fewer features than the year old PLUS III. The single most noticeable feature appears to be the $99 price. This is cheapest trigger that Pocket Wizard has made. Mike Kelley did a review over at FStoppers.com. David Hobby also reviewed and liked the PLUSX. I've added the PLUS X to the trigger table and reader poll.
I found what was the most interesting aspect of both reviews was the reader comments there were a couple of interesting themes that kept popping up in the comments of both reviews:
I think the PLUS X is a move by Pocket Wizard to better compete with all the Chinese made triggers. It's really tough to figure out if this new trigger is worth many times the cost of the Chinese made ones.
