Love, love, love my scale! So much easier than using measuring cups!
When I first started, I had to have a calculator handy, so that I could convert the cup measurements into weights.
I made a chart to indicate the weight of 1 cup of the most used ingredients, but I'd still have to use the calculator when the recipe called for fractions of a cup (i.e. 1 cup of sugar = 7 oz, 3/4 cup = ?)
Finally got smart. Made an Excel chart with the weights of 1/4 cup all the way to 5 cups for both my flour and sugar, and taped the chart to the cover of my storage container. Now, if the recipe calls for 2 1/4 cups of sugar, I can just look at my chart and find the weight.
I have two scales. I have a Salter Aquatronic, which measures in 1/4oz increments, up to 5 lbs. I love that one, but it's getting old, and the lcd display is losing a couple of markings.
I bought another Salter on sale as a backup, that measures in 1/8oz increments, up to 11 lbs. However, that one is much slower to turn on, and tare, the display is much smaller, and the default measurement when you turn it on is grams. I really don't like this second one, and I'll be really sad when the first one is truly dead.
