astrostar and some of the other name brand remote starters are going to be the most expensive but they are going to have that longest range from 2000 to 3000 ft. Some of the cheaper remote starts will work just as well but most only have a range from 300 to 400 ft. just make shure that it has the ability to run a 15 secound delay and is able to read the tach signal so the engine will crank longer.
