Motorcycle Alarms

Does anyone know anything much about motorbike alarms and immobilisers?
Working in the city, I park my 250 in front of the bar so that the bouncers can watch it. The amount of times people would come and fiddle with the bike and have the bouncers scare them off is quite disturbing. I park my bike in many different places, and as I will be riding my ZX9R around everywhere soon, I want to be able to scare those idiots off as well.
I don't konw anything at all about motorbike alarms so any tips would be great. All I can findo n Ebay is this one:

has anyone heard of this brand? Anyone know what it costs to get this installed?
