ok , lets see if this helps;
I bought a 2way rs with window options and extra siren for under my dash , this alarm does everything , i purchased it through a electronics wholesaler in my area for i believe 250 or so , it is a hornet i can not recall the model number , anywayz hornet is a Dei product the same company that makes clifford and viper, as far as getting installed, i suggest the following, go to best buy and see if you can get one of the kids alone and see if they will put in in "on the side" they don`t make **** for money , they do it all day , i had one tell me he would do it all for $160 window options and all, i have had prices between 200 and 250 elsewhere, these alarms are complicated and take time, i still haven`t had mine put on yet do to money issues and starting a new business, but hopefully this answers your question, or if you shop around and can`t find a good deal and do your research and you like this system let me know and i could get you one perhaps, also i can`t recall the name brand but i say it on ebay , they have one that you can monitor online , you can shut your car down via internet and track it using gps, i t this it is put out by alpine, mine has two way and can turn on and cool the car at what preset temp you want and turn off keep the car warm or hot, plus you can turn your car on from up to one mile away!
