>EDIT: It appears that the "Digit" brand is just the same brand as American Weigh, the manufacturer of the original scale. Makes sense, seeing as they seem to share a design.
They sell it as the Blade-100 as well. https://www.amazon.com/American-Weigh-Scales-BL-100-BLK-Digital/dp/B002SVLB8E
Been using an AWS Blade for years and never had an issue with it. You can get them in a ton of different colors and either 1000×.1g or 100×.01g.
This is the one I use. It weighs down to 0.01 and is foldable so you can put it away. Usually meant for weed, you’ll hear it called a blade scale.

I don't put a ton of weight on a special setup instead favoring starters as a better way of yeast health. A paint mixer or egg beaters would work too.

I like my Cereal Killer for the 5 gal batches I run it through. Some like Monster Mills
>a scale for minerals
I like this one from amazon
>a sightglass for volume.
I use a tape measure.
Yeah, I have a small one from them that I use for weighing out hops for homebrewing. They work great. The one you linked is probably a better size.
It's Acaia and the Pearl fits just fine on the drip tray of the Rocket if you are willing to spend $140. If not, you can buy the hario drip scale or something like this small AWS scale and it should be good enough.
I have this $15 AWS scale from Amazon (https://www.amazon.com/dp/B002SVLB8E/ref=cm_sw_r_cp_api_i_aYEFFbBNND25E). I’ve never had an issues with it and it can measure as little as 0.01g
Looks good to me. Invest in a scale. This is the one I use
This is a great one too. http://www.amazon.com/American-Weigh-Scales-BL-100-BLK-Digital/dp/B002SVLB8E
If I were to do it all over again, this is what I would do:
Purchase all my flavorings, PG, and VG from one site (BCV, Gremlin, etc.), instead of buying from all over the place and wasting money on shipping.
Purchase a scale like this one
Purchase 15ml or 30ml plastic dropper bottles off ebay like these
Look up tutorials on how to mix by weight and that's basically all you need to get started.
