A digital scale with 1-gram resolution is the single biggest accuracy upgrade you can make to baking, cups and spoons vary batch to batch, grams don't. Look for a large enough platform to hold a mixing bowl and a tare function you'll actually use.

Escali
Simple, accurate, and has stayed a baker favorite for years because it does the basic job without extra features to break. The display is small and the platform modest, a large stand mixer bowl can be awkward on it.
OXO
The pull-out display slides out from under a large bowl so you can actually read the number while weighing flour into a mixing bowl, a real usability win over scales with the screen under the platform. It's bulkier to store than a slim, low-profile scale.
KitchenAid
A solid, inexpensive scale from a brand already in most baking kitchens, fine for standard recipe weighing. It doesn't hold precision at very small gram amounts as well as a dedicated precision scale, not the pick for exact spice or yeast measuring.
My Weigh
A favorite among serious home bakers and small bakeries for its high capacity and consistent accuracy at both large and small weights. It's a bigger, more utilitarian unit than a countertop kitchen scale, not the prettiest thing to leave out.
Etekcity
One of the cheapest scales that still reads reliably to the gram, a fine choice if you just need to start weighing ingredients and don't want to spend much finding out if you'll stick with it. Build quality and long-term durability trail the Escali and OXO.
