That's the one I ended up with. I haven't had any problems with it so far, and I've had mine for about 4 years. That one is manufactured by Elbox. It is also sold by Eyetech as an "EZ-VGA" scandoubler; despite the different name, the hardware is identical.
Remember that if you haven't had any problems with your existing scandoubler, there's no reason to spend £80 on a new one. The switch on the back changes something-or-other. I can't remember what exactly, but one position may produce a better image than the other depending on your motherboard. In practice, I found I had to keep flicking between the two positions to stave off the overheating problems for slightly longer.
