The charge master is a very nice scale, very accurate.
What are your needs: Are you looking to load for rifle precision shooting or for handgun plinking?
Whats your budget?
You can look at it in 2 ways.
If your just starting out you may want to buy a less expensive beam scale and upgrade as you go along or you can buy something deluxe like a charge master but only have to buy one scale.
The nice thing about dispensing scales like the chargemaster is that it is automated, you punch in the number of grains and it dispenses it for you without you having to fidget and trickle the grains onto the scale.
As far as the dryer sheets, it does work to an extent.
My wife saves all the old used ones for me and i just add one or 2 in with the media and they do collect the dust nicely.
