Security Alarm

[Grip72]

Ok in my small town there has been ALOT of recent thefts and break-ins of cars. This once the thieves stole a radio deck, like a normal stcok one, it wasn't even a cd OR tape player. Very despearte and then another 2 -5 cars were stolen and another 5 at the dealership were attempted thefts. Anyways, this never used to happen in my small town and stereos have been being stolen left right and center. I"m really worried about mine because everyone can hear it and my house is really easy to find. So i am going to buy a sercurity device. Any recommendations? I don't want to spend a whole lot of $$$!
