So there are a ton of cheap ones on the market, any recommendations on a solid, precise one that will read in gravity.

I figure nearly all the cheap ones are the same Chinese POS rebranded, who builds quality instrument at a fair price.

I don't know how cheap is cheap, but this is the one i've been using for the past three years.

ATC is more important than getting one that reads in gravity. It's pretty easy to consult a chart to translate from brix to SG.

Check out brewhardware.com. It's a really good one plus you'll be supporting a fellow HBT'er, BobbyM. Great service also.

Disclaimer: I totally haven't researched this prior to posting, but can refractometers read after fermentation? I had previously understood that they didn't, but I've seen an episode of brewingTV where he mentioned reading from the refractometer and adjusting for reading fermented wort.

Once alcohol is present, it skews the reading. There are calculations that will get you close, but I just measure FG with a hydrometer since I want a taste anyway.

More info on the calculations can be found at http://seanterrill.com

This is where I got mine and could not be happier.

How close is close? I've avoided getting one if they're only good for OG. I will never gave an issue with taking a sample at FG, because I will taste. But I'm a data junkie and I might consider getting one if it provides reasonable estimates mid-fermentation.

I actually haven't bothered trying it yet, but I've heard everything from within a point or two to wildly inaccurate. I have two batches to bottle soon, so maybe I'll give it a whirl. Even so, they're still handy if you need to check fermentation status. The reading may not be accurate without calculation, but you'll still know whether or not the sugars are dropping with only a tiny sample.
