This is the one I got. Good quality. Plus you'd be supporting BobbyM who is a fellow HBT'er and homebrewer.
I agree. I bought mine from Bobby, and when I posted questions about how to use it, guess who answered...?? Bobby from Brew Hardware.
Get the model that has Auto Temp Calibration (ATC) is was under $40.
In addition, I slightly disagree with the comment about checking calibration every 5 brews. Depending on where you brew (outside vs inside) the ambient temperature of the air plays a role in the accuracy of the refractometer.
To calibrate correctly, the distilled water sample and refractometer should both be around 68 degrees F, BUT most important is that they both are the same temperature.
For instance I brewed outside yesterday in northern VT and it was around 48 degrees outside. I brought refractometer and sample outside and let them come to that temperature and then calibrated.
The ATC aspect of the device will "correct" the readings as long as the temperature does not fluctuate much +/- 20 degrees.
