Remote car starter?

I'm looking for a remote car starter for a 2004 Honda pilot. I know there are a lot of different manufacturers and different options. Does anyone have experience with Hondas with car starters? Will an after market product void my warrenty? I am planning to purchase a kit and have it installed by a proffessonal but the two local installers that I'm considering sell two different types. Any input would be appreciated.

As far as which brand is the best, I don't know. The remote starter will not void a warranty. If it has to be disconnected for warranty work, the warranty does not cover that part. You would pay 1hr of labor.
