I would go against the majority here and say DONT get a Truspeed, I've got one and never use it now, it has a habit of cutting out when used  on some of my quicker cars, just a quick power loss but enough to disrupt your rhythm,

This is a known issue with a few earlier models and doesn't affect the latest ones. It is easily fixed with the connection of an extra wire. Talk to Steve for instructions if you are competent at soldering or send it to him for modification. He sorted mine in a couple of days.
