Go to Lik-sang. I purchased the Sagestar YpBSpr (!) VGA box from them and it's good. The Blaze one I had but it was utter cack! Bloody big yellow bar on my screen! Also because the monitor has such a fine dot pitch the games ended up looking really aliased (jaggy). The Sagestar one makes games looks just like your playing on a TV with Scart or S-video. Anyway
