Those are one (among a lot of other brands) available to the Asian market. I don't have first hand information on the quality of this particular model but if it's anything similar to Innovatek VGA (available in North America and Canada - check google), they have a few minor "annoyances". Among these, but not limited to - is the the resolution size. I think you can only default to 840x480 and not 800x480 that most of us are all used to. While most Lilliput and Xenarcs are also assembled in Asia, a stricter set of quality standards are imposed on the Xenarcs and lillis since they are aimed for the north am market.
Please - no flames - I'm not saying that asian brands sux and I don't want to make a generalization - but for the most part, a lot of these asian clones are cheap quality and aimed at a different market. I went through 4 "no-name" brands before settling for a xenarc. btw - I'm asian
