Yeah, you have to Google it and then they have it as part of their 881/2/3/4 family. The range is where they differ, the 871 is 0-85% Brix whereas the 884 is 0-50% Brix. Resolution and Accuracy are identical. Keep in mind that 50% Brix is 25% alcohol v/v so the added range of the 871 really buys nothing for beer brewing.
Just checked Amazon and it's currently $79.99 with free Prime shipping.
So I made the move and bought the 884. Really nicely made and quick and easy to use. Checked it against my cheapo hydrometer and was spot on. I can see lots of uses for it: Check condition of a starter: When to ramp up a lager temp. for DA rest; Readings over several days to confirm completed fermentation; etc.
Reads in brix but Northern Brewer has this tool

Bought it for $79.99 + free Prime shipping.
