I have been looking into getting one and found this one at the Yahoo store:

Not a bad price. Cheapest one I could find (this is the modular frame, they also sell a welded frame which I assume is a little bit stronger.) Looks like in pops in and out quickly too.

I try to stay away from anything that uses wing-nuts.

The Nissan one isn't cheap, but then, neither is the quality of it.

I think my sister-in-law has that same divider in her Tahoe. Haven't heard any complaints from her. She's got a full grown black lab, pretty much like the picture. But I agree with Ian about using the Nissan one.

The only thing I am worried about with the Nissan model is the ability to put it in and take it out quickly. When I read the installation instructions (on xterraparts.com) it seemed that once you install it, it is "in there", and is pain to take out quickly.

The model I posted a link for looks like it would be easier to put in and take out. But, like you said, "wingnuts". You are probably o.k. for the first 20 installations, then it won't want to tighten the same way anymore.
