The TwEECer will hold 4 positions for your car, and it comes with a rotary switch. The Quarterhorse is a good alternative, and I believe it can be equipped with a rotary switch as well. If you have any inclination to tuning yourself, the Quarterhorse is definitely the way to go. If you want to check one out, I would be happy to demo one for you.
