Anybody got any experience with these alarms? Tossing up between the SR-i900A or the SR-i1100 The i1100 has GPS tracking, but what is interesting is that Scorpio's own website doesn't seem to mention that model. has it been pulled? One of the motorcycle places sell both models. Just wondering if anyone knows what's up with that, or if anyone has any comments about any of these units? I know that the GPS module can be bought separately, so maybe the i900A and the GPS module is the go?
