If memory serves me, the Shooting Chrony is upgradable. So, if you're on a budget, maybe get the Alpha. Then, as you can afford, send it in and it can be upgraded to have the exact same features as a Beta would have. The cost, IIRC, is minimal. Call MidwayUSA and talk to a tech rep. They should give you straight answers and they have great prices and even better customer service.
Help you any?
