Mike is looking for a car video unit that he can install. He's building a small fleet of rental cars and wants to include them as a feature. Leo says there's a lot of places to buy Chinese consumer electronics, like eBay, and they're cheap. But the quality varies considerably and he'll have little recourse if they go bad.
Leo advises buying one and check out the results. If it pays off, then he can maybe get several more. But the quality isn't all that great and standards are often ignored. One place he can check is MadeInChina.com. It's a clearing house for small manufacturers and they will at least stand behind what they represent.
