Scooter,
We had the bushnell radar gun, the cheaper of the two....is that the speedster?
Anyway, after less than a year of use the plastic trigger broke and while it will still off and on, it will not register speeds anymore. You get what you pay for, I guess.
Accuracy, however, was within a mph of a a borrowed Jugs gun we used.
If I had it to do over again, I would definitely order the more expensive of the two guns.
