Quite right Tim . As Lomoto has pointed out the others don't work for the Z, he has obviously spent his own time & money in looking into this and (as I have met Lomoto) I have absolutely no doubt whatsoever that were the other nets to have worked he would be selling those nets at the fiver price you have quoted. Instead of pointing people to nets that wouldn't fit he has been offering nets that do work to members cheaper (and a damn sight cheaper than Nissan btw).
