Car Alarms: Car alarm and remote start, valet 562t, galaxy line

Question
I have a 1994 BMW 740i, with Valet 562T remote start/remote entry. what type of full security would you recommend,(3-6 types) an excellent model that incorperate the existing equipment already installed? also how is the quality Galaxy line of products?  

Answer
The Galaxy products are decent, not what I personally consider high end, but they are reliable.  If you pick up a 563T it will incorporate mostly the same harnesses and add security.  You will need to hook up a little more than what is connected currently but the color coding for the two systems would be the same.  Here are the installation manuals for both the 562T and the 563T.
