Alarm

[Wrighty]

Ok, here's my conundrum. I have a mark 1 Punto, which I have had de-locked and had an aftermarket R/C/L kit fitted. However, I would like to install an alarm onto this system. I am sure that it is possible but I don't know what is the best product to use. I am not looking for anything fancy, just the basics inc blipping noise and flashing indicators. Can any recommend any products for me? Baring in mind that I have a fairly low budget. Thanks
