I had Chrony's for years. Then I bought an Oehler 35p. I have been spoiled. Yes it does take longer to set up. I haven't timed it but I'd say the most time spent is looking through the screens from behind the rifle to get it all lined up. It depends on what you want to do. I load for arms that do not have too much in the way of information for loading, and so use the Oehler and PressureTrace to keep things under control. If I had an '06, a bunch of powder and bullets, then sure, a Chrony or other less expensive chronograph would do the job.
