Hi there, you have the choice of two types:
DIGITAL -
PROS: accurate; would look better sitting out in the kitchen
CONS: expensive, batteries need replaced, life-span limited; if you're messy like me you might spill liquid on it and break it.
MECHANICAL -
PROS: cheap, lasts for years, no batteries
CONS: less accurate, looks basic/retro, so you might want to store it in a cupboard.
I'd advocate a scale with a broad flat surface, so it could be used with any container.. Given that you might bulk cook/bake, it should weight up to 4 or 5 lbs, plus be able to be adjusted to zero, so you can add extra ingredients and weigh them easily.
Given that I cannot be bothered with batteries, this would fit the bill best for me:

These ones are OK for me, but if you wanted to weigh stuff straight onto a plate, the plate would cover up the display and make it hard/impossible to read:

If I wanted something digital, I'd go for something like this:

The features I like in that digital model are: it switches off after 3 minutes, so batteries won't be used up accidentally; the display and control buttons are large and easy to read; it looks easy to clean, it takes rechargeable batteries, and I could cover the control panel with sticky-back plastic to protect it from spillages.
I'd suggest that you decide what you need first, then look at some of the reviews on Amazon to get an idea of potential problems.
Good luck.
When low-carbing you needn't be ultra-careful about measurements, so small variations of an ounce or two shouldn't be significant, especially if you use Dr. Atkins' advice about food choices. It's a good idea to stay on the induction food choices, and just increase your carbs by adding in extra veggies. More carby induction choices are onions and tomatoes, which add so much flavour to food, and avocados, which are a simple snack you can eat anytime.
Good luck with your diet.
