Clifford Security Systems

[AHels]

Although not entirely Hummer-ish, I'm hoping someone here have some experience with the various Clifford systems available out there.

Trying to make my mind up between the Matrix or G5 system but not getting very far :/

I'd love the 2-way remote included with the Matrix (RSX3.5) systems, but it seems there are more accessories available for the G5 (avantguard 5) system. Specifically looking at the smartwindows, blackjax and proximity sensor modules.

Been trawling the web for some time now, and keep drawing blanks so here I am

Can I get a 2-way 'remote' for the G5 system? or can I get the extra modules listed above for the Matrix system? Or should I be considering something different all together?

Basic features I need are remote start, windows and proximity sensors. Anything else is purely extra.

Comments/Opinions appreciated.
