I looked at the stock Ford one but at $460 on eBay it's pricey for stock.

I want an OEM upgrade, in that I want one that uses the Ford remote and doesnt need an extra one.

Been looking at Viper (http://vipersecurity.com.au/), Dynamco (http://www.dynamco.com.au/) and Mongoose.

Anyone have any suggestions on these or others?
