green machine

my truck has power locks but no alarm or keyless entry. what would be a good aftermarket system to get for it? i saw some on ebay for like $30 but i dont know if they are any good. im hoping to keep it under $50 but i am open to all suggestions. thanks

You might not, or maybe you do, read this link, especially the last post on page two, this guy was told by two diff dealerships that he did not have the keyless entry, but he found out he did.
