i worked for best buy as the senior installer for 5 years and installed many viper rs units. very rarely did i have any problems with the units themselves. usually the issues were related to bypass modules or specific issues with interfacing with a particular vehicle. they are good overall units and the one button system is pretty simple to install and use. not sure if you have talked to them about a price quote yet or not, but make sure you budget more than just the unit price. there is also a bypass module you will need and possibly need to run power from the battery for it.
