Harbor Freight now sells two scales that are really inexpensive. I purchased another offering they had a few years ago, and its pretty accurate. I've been happy with it. Here are two links to the ones they offer now.
Digital Pocket Scale
1000 Gram Digital Scale
"Duker" As far as CCS and rods, I still use the coin method as weights, but also include quarters nickels and dimes. I then take the bag, set the scale to grains, and measure the actual weight.
A cheap scale like the ones posted above, can help simplify things.
