Like anything else shooting, the shopping is the fun and the frustration!
A friend and I purchased a Chrony brand Beta as a starting point. Considered it mid range of the basics.
My eye has been on the PACT since the beginning, and if I had the cash today I would purchase it. I have heard a lot of good about the PACT, and their ability to provide readings, printouts and tie in with other shooting electronics is why I am looking at it for my gun room.
By the way ... The Chrony brand is a tough machine. Its all steel case that is a self contained closed case is really strong, and its electronics survive abuse ... outside of the dreaded shot down the middle of the body

I actually shot on of the skyscreen wires, and it made no effect on the chrony. I have heard of others shooting their skyscreens and the electronics being damaged.
So ... Talk to others, oooops that is what you are doing here. Talk to as many as possible, go to online catalogs and read the reviews, and poll people like USPSA Range Masters for what they like. These people set them up at matches, and they need to be consistent, reliable and accurate, because the fun and careers of shooters are hanging on their readings!
