I've seen way too many of these posts, especially that part about excluding ebay? That's where I got mine and I had no problems with it. Ironically, ebay will prolly be your best bet (and cheapest place) since these things come from Hong Kong/China.
That's prolly the most basic one without sacrificing any functionality. They sell better versions too, of course, and there's a cheaper one, but you won't be able to plug in a VMU.
