I have seen these once or twice across the interwebs over the years, mainly as custom made boxes. I was looking through eBay over the weekend and came across someone selling ten of these at £35.00 each. Anyone tried them before, are they any good? They look to be a product manufactured by Teknovo (http://myteknovo.com/) from one of the supplied photos... Ted.
Ah wow I remember seeing those things. Been a while. Never tried them though. I got one of the straight VGA cables from china on the cheap...
I think that one you showed will work - however I once got one that was the same but the SD reader and vga box was at the end of a lead (as opposed to staright at the back of the console) and this played havoc with the SD reader. Also the soldering and workman ship inside the box was awful - (literally some of the worst soldering I have ever seen lol)
