Hey! I bought one of the cams you are talking about on ebay, in fact from the exact seller of that item.
here is the topic I started (with the link to the item)
BTW, I ordered the 50mW one, and that one didn't work, so the very nice seller sent me a new one free of charge, and it turned out to be the 200mW one (which is cool) it works great, and I'm very happy with it. the picture quality is great for what it is.
I don't think any of those are that good particularly, but this one you mentioned is just extremely small, I mean, I'm putting it in a tiny lego canopy on a car or plane I have here.
