Cheap refractometer?

[uberlink]

I asked this in another thread below, but haven't seen any response yet. Thought I'd give it its own thread.
I've seen the following for sale on a popular auction site: "INDUSTRIAL GRADE Salinity Refractometer with Automatic Temperature Compensation (ATC)"
There are several other variations available on the site, ranging in price from about $25-$40.
Has anyone ordered any of these? Can you offer any recommendations? I'd hate to waste my cash. Thanks.

The important thing is the ATC, if it has that I say buy the cheapest one you can find.

Yes! I just answered this in your other thread as well. I bought mine and paid about $30 for it. Works great

I bought one off the famous auction site for $26 plus shipping - has ATC and so far has worked great.
