(listing is on my local trading site, but the same Chinese product is available all over the world)
They work brilliantly in my experience. I've used them with both LCD and CRT monitors. Some experimentation with the display resolution may be necessary to get the aspect ratio right, but I've been delighted with the results for the price. No issues with ghosting or ringing at all.
