I had the same problem back in 2006 and 2007. Unfortunately, such devices were not available for my Nova DVR at that time. I made up my own out of wood. Cost was wood scraps and about an hours work, plus a hinge I had on hand.

The making of this was published in the January 2007 issue of More Woodturning, if you would like a copy of the story, e-mail me and I'll send you a copy of the article. Incidentally, I'm still using this device four years later.
