Yes, there are scales that can measure in 1 gram increments.
My scale is an Escali Primo. It has a capacity of 11 pounds, and a
resolution of 1 gram or 0.05 ounces. Besides that, it's very compact
and easy to store. It costs around $25-30. I bought mine at a
homebrew supply store. (Making bread and making beer have more in
common than you would think!
As far as I'm concerned, a digital scale is a necessity. It makes
baking so much easier. I put the mixing bowl on the scale, zero the
scale, add the first ingredient, zero it again, add the next
ingredient, zero it ...
It's one of my favorite tools. I don't know how I baked all those
years without it.
