The "slow" speed setting on the Hornady actually does not change the total time for dispensing a complete charge by much - a couple seconds at most.
The way the machine runs is that it starts slowly, then ramps up the speed, until it is fairly close to the finished charge weight. Then, it slows down - to trickle the last couple of grains. The speed setting only changes how long the machine runs at the "fast" speed....and thus, how close it gets to the final charge weight before slowing to a "trickle". If it runs too fast, for too long, then momentum can cause too much of some powders (esp. long stick powders) to tumble out of the tube - and thus the charge goes over the specified weight. If that happens, if the unit dispenses more than 0.1 grain over the specified weight, the unit stops and an "over" alarm sounds.
The slowness of the dispensing speed, to which I alluded in my last post, can be largely overcome by "multi-tasking". I run a few charges, then start seating bullets, as the machine continues to run. So, when I finish a tray of cartridges, they are complete (charges weighed, dumped, bullets seated and crimped). Done and done. The process isn't that slow if you multi-task.
As for "the expense" of maintaining electronica, as you put it, Mr. Guffey....there is NO "expense". Solid state electronics - either it works, or it doesn't. As for myself, I'll take the vagaries of "electronica" over weighing each charge on a beam scale, every time. Now THAT is a slow process, not to mention TEDIOUS.
By the same token, if I had a hole to dig, I would definitely choose one of those new-fangled shovels.....over trying to dig a hole with a rock. I'm just funny like that.
