Looking to get a cheap, reliable TDS meter. Anybody have a link where I can get one, ideally under $50?

Lol, I just used mine like 5 minutes ago.  I bought mine off ebay about 3 months ago.  Here is the link to the same one.  It seems well made.

My new TDS meter was waiting for me in my mailbox when I returned to Houston from Dallas.

My tap water reads ~335 ppm TDS.  Rainwater collected from my roof reads 27 ppm TDS.

Water in the Utric pail of my outside bog garden reads 35 ppm TDS.

I got the model you linked to above.

How often does it need calibration, or will the calibration never get so far off that i can't really trust it for this purpose?

The meter was made by Hanna instruments, so it WAS very well made.

I have a pH/Temp meter from them I use in brewing beer.
