Reverse sensor

[Paraphoe]

Can anyone recommend a good quaility, fair priced reverse sensor for my X? It would help me out a lot with parking. I'm looking for something with LEDs, beeps, or both.

Thanks in advance.

Anybody have any experience with sensors like the following, on eBay:

Are they good quality? Prices seem a little low, so quality is a concern. Also, does anyone know if the beeping features on models like these can be disabled, or volume lowered?
