I know it’s spendy, but this is my kitchen BFF. (It goes to 11 lbs, so you can also use it to weigh packages

Yes! I use mine for everything I eat--it's amazing the difference it makes! For example: one serving of the Quaker rolled oats that I eat every morning for breakfast is 1/2 cup or 40 grams. A 1/2 cup leveled off and perfectly even is 60 grams. That's 1.5 times the calories. Every day, that adds up. When you add in high-caloric-density items (e.g. peanut butter) . . . It makes a huge difference.
I initially bought a cheaper $12.00 (or so) scale, but eventually upgraded to the Oxo 11 lb. capacity scale. I love it because of the pull-out display, backlighting, and high-caloric-density for when I use heavy cermaic mixing bowls when cooking. Here is the link:

Honestly, if you don't have the funds for the Oxo scape though, seriously just get any kitchen scale that looks convenient to use. There are a ton out there and all of them are bound to be more accurate than volume measurements.
Right now I have the Inspired Basics tempered glass scale here. If I had it to do over again, I think I would have invested in the OXO scale with the pull out display here.
Whatever scale you get, consider how you plan to measure everything. I have a toddler at home and not creating extra dishes or spending extra time measuring is critical for me.
If you want to measure directly onto your dinner plate, make sure you get one that has an angled display and/or the display can be pulled out (this is why I regret my choice a bit). If you want to be able to put your container of food directly on the scale, tare it, and then measure the difference, then you'll need a flat digital scale.
I love my OXO. It has a nice wide plate that can accommodate all sorts of produce and unwieldy objects, and a pull-out display for those occasions when I'm scaling onto a wide bowl or half-sheet pan that would otherwise obscure the readout on a smaller scale. There's also a backlight you can click in when it gets dark in the kitchen. It switches between ounces and grams, no prob, and the latest version of this scale can do ounces-only, rather than splitting measurements into pounds and ounces.
For small measurements, anything under 4g, I recommend a jeweler's scale like this one. Measuring anything under 1/8th of an ounce is a real crapshoot on large format scales.
