I've been doing some research on electric horns/bells for my commuter bike. I'd like to find something that sounds more like a scooter or even a car horn (not as loud, just a similar type of sound) than the traditional ding-dong bicycle bell.

I found this QBell electric buzzer made in Korea:

I have not been able to find any more references to it, nor have I seen it sold on eBay or CraigsList.

Has anyone heard of that particular gadget, or does anyone know of an outlet where they would sell it? Any information will be greatly appreciated.

Just as an additional reference, these are the other electric horns/bells I've been looking at:
