(I do my best to not buy from Amazon but) Here is the scale I and it seems everyone else who posts on here has. Or the exact same one that’s rebranded by a number of different sellers.

I'm using a maxus one from Amazon. Looks like a rip off of the weightman one. The one I'm using seems discontinued, but is similar to the linked one.
Great Scale $11
WDT Tool $15
Gasket, Screen, Dispersion Block $50

i'm fairly new to espresso but after searching around decided to get this one. $11, 1000g max weight, and has a builtin timer. So far happy with it!

Other people are saying you need to spend $50 or more, but I actually spent a bit of time trying different scales when I first got into espresso and found a really good one (if you're in the US)
It's super cheap, has 0.01g precision, is incredibly accurate (I tested it with calibrated weights myself and it was spot on), is pretty fast, and has a timer:

I tried a bunch of different scales and this one was far and away the best, and also at the best value.
If you search on Amazon for "coffee scale" you'll probably see a few companies selling this same scale but slightly different, but all the same dimensions. Couple of examples:
