Summary: They're cheap and capture video, but don't buy the Sony Handycam HDR-CX190, CX200 or CX210 thinking that you're getting a great bargain on a real HD camcorder. If you're going to buy one, get the cheapest; nothing on any of these is really worth the extra bucks.
Pros: Sony's entry-level Handycams, the HDR-CX190, CX200 and CX210 are small, lightweight and cheap. A captive USB cable that enables charging while connected to your computer is one of the few perks.
Cons: You can't really call the video HD quality, the camcorder feels flimsy and the lens is prone to fringing.
