I'm poor so I saved my pennies and upgraded from a traditional chronograph to a Magneto Speed. Rick is right, the features of not having anything in front of the bench and not having to worry one whit about light conditions is cooler than ice cream. For quick, easy, inexpensive, and light, I don't think the Magneto Speed can be beaten at this time, but it inherently lacks some of the capabilities of the Doppler system and I'm sure it isn't quite as accurate. For a hobby shooter, hunter, and general tinkerer like me it fills the bill wonderfully, though, and the whole thing including the foam-filled pistol case it comes in weighs less than two pounds. There's an economy version with fewer mounting pads out now that runs about $180 and fits into a plastic case exactly like the ones used for five pounds of stick welding electrodes.
