I've been waiting for them to come down in price also. I got in on the group buy a year ago or so, but had a LS gasser at the time with power, heat, etc. I traded that truck in, and sold the mirrors when I got my Dmax.
My Dmax is the work truck model, and need a Manual pair. But those are still going for $400. Ouch. I checked back with the group buy vendor, and no luck. Same price as everyone else. Hopefully someone will find a better price somewhere.
