I started racing two years ago using an X-Car 45A, which worked great until I smoked it with reverse polarity.

Since then I've owned at least 6 TrackStar 120a Turbo Gen1 and they've all been terrific value for the dollar amount. When I was running in stock classes I was plenty competitive with folks running some high-dollar gear.

There's a couple of dedicated TrackStar/Hobbyking threads out there with opinions, so don't forget to look around there.
