You are right on the money bigdaddy, I did not have a need to buy the dispenser until I started shooting calibers that like the long extruded powder (25-06, 375 Win, 30-30). Until I started fooling around with them all I used was a Hornady powder measure, and still do unless I am using the long extruded powders. Another thing to consider is the Hodgen SC line of powders that are supposed to go through a powder measure with good repeatability.
Another good use I found for the dispenser is that it is very fast when making up loads with different powder weights when looking for accuracy. Punch in a number, weigh 5 loads, punch in the next weight and keep going.
