Hi all (Posting from Recife at the moment.),
Im having a great time here. Looked at some buildings for possible purchase today.
As to th current topic, allow me to add a few comments. First, wqarranty issues are not what they may seem. If the op decides to DIY, his warranty source is the online store from which he purchases the hardware. If its a professional installation the warranty source is the installing company. In either case, the manufacturers warranty is never *directly* to the end user.
Online stores have significantly lower overhead than traditional alarm companies so their prices are almost invariably much lower. The down side is that you must do your own installation (not so hard with wireless as some believe but not simple either). Also, with a professional alarm, if theres a problem the installing company fixes it. With a DIY job, *you* fix it.
Im biased in this regard since I sell onlin but I think Im being err, =A8"fair and balaqnced" on the sunject. :)
