The thread about trajectories and zeroing got me to thinking it would be nice to have a chronograph. Even though I don't reload anymore, it would nice to know how various ammo I shoot is really performing, and how consistent it is. I haven't kept up with the technology. So, have at it. What are the good brands, the features to look for, and likely street prices? Since I'm not reloading, I don't want to spend too much and probably don't need a high end model. I'm looking for portability, reasonable accuracy, and a good value cost-wise. What say you?
