First, in case you are tempted to buy something cheaper than an Acacia or even a Brewista, and IMHO there is a very good "bang for the buck" reason to do so, remember that not all scales depict to the tenths of a gram. Make sure whatever you get, does that.
Now to the "bang for the buck" consideration. I've tried several low budget scales over the past 10 years, way back before the benefits of weighing were as widely accepted as they are now. Back then, I hadn't even heard of Acacia or Brewista. I also knew that jeweler or "drug dealer" levels of precision are not required for dialing in and repeating excellent espresso. As with the watch hobby, "maker-minded" people have come to know that there are certain standout, "cheap Chinese" products that perform way above their price. In watches, Invicta brand gets and deserves little respect. They rarely are any better than their $100'ish price tag dictates. Rarely, but not never. There is one, that has the movement of a much more expensive Seiko, and it's still only $125. This is the kind of thing maker-geeks figure out. The cheap scale I've come to like is this one: http://www.harborfreight.com/digital-pocket-scale-93543.html
I've got one in each home.
It used to be $20 regular price and $13.99 on frequent sale. It only weighs out to 500g (half a kilo) where most of the really cheap scales weigh out to a whole kilo, suggesting more granularity in the stroke of its load cell. It's way more stable and of higher quality than some of the other cheap scales out there, even ones with fancy metal platters and blue backlit displays.
The drawback of this type of scale is that its platter is not big enough to put a whole portafilter on. No matter to me as I have a super low/zero retention grinder and weigh into a yogurt cup before grinding. And it's perfect size to put your demitasse on it, under the group for weighing your extraction.
Just thought I'd throw that out there. I understand why you would want
something more blingy. I'll probably get an Acacia just for the fun of it, if I don't find some other fun frivolous coffee thing to buy this summer. But I don't have any illusions that it will improve my espresso in any measurable (pun intended) way.
