1/10 of a gram?! Really?! 1gm or 0.1oz is common. But off hand I can't think of anything I'd weigh in tenths of a gram -- which is 35/1000 of an ounce -- in order to follow a recipe.
Anyway, you can certainly buy that kind of resolution; but it's not common in scales that are used to weigh more than a kilo; and when you find it, it tends to be expensive.
For most cooking purposes you should be above to find something perfectly fine for less than $30 on ebay or at a digital scale specialty e-tailer. There are lots and lots of choices. Personally, I wouldn't worry too much about tiny inaccuracies. Almost all the digitals are pretty darn accurate; most metric (measuring) inaccuracies are the person and not the machine; it's unlikely you'll spoil a recipe for making an error of 0.1% (1 gram out of a kilogram) -- which isn't even that good by modern, scale standards.
It's probably pretty hard to find a scale that doesn't tare nowadays. But it's worth making sure.
Anyway, here's one site: Kitchen Scales
Note that they sell Escali for less than Escali. The parent operation is AmericanWeigh. I've bought from them a couple of times. NP.
Here's another: Kitchen Scales, Food Scales & Cooking Scales
Will Knott is an excellent resource for this sort of stuff, and funny to boot. I should have listed it first. Also, personal experience and NPs.
I've never actually with these people but they have a good rep for reliability and low prices: SaveOnScales.com - Electronic Digital Scales, Pocket Scales, Gram Scales and more!
This place, ditto: Diet/Kitchen Scales - Cyberscale.net - Digital Scales & Pocket Scales Diet/Kitchen Scales
And of course, there's Amazon.
In addition to the usual suspects like Salter, I'd look at Taylor and My Weigh especially. IIRC, Michael Ruhlman was waxing very enthusiasitc about a My Weigh 5000 with an eco-friendly bowl (read "hemp-plastic") he liked for baking and charcuterie.
There are a lot of memory features going far beyond zero and tare that let you add ingredients, remove and replace the bowl, and so forth. You want.
You also want a scale that runs on batteries you can get anywhere, like AAA, AA or 9Vs.
Here's a direct link to My Weigh; but it's info only, they don't e-tail: Home Front | My Weigh Digital Scales- Manufacturer of quality digital scales and digital scale accessories
If I were buying a scale, I'd get a My Weigh 3001 (or a 7001 if I baked in serious quantities). No way (forgive me, I can't help myself) would I spend twice as much on an OXO.
