Buckeye hydro has a bunch to choose from. I bought a basic one three years ago and it still is going strong. I think i paid $25.

If you have an RO/DI unit, get the inline ones that read both In and Out (although in doesn't become that important after using it once).

A better choice with an RODI is a 3-Probe meter (the TRM1 is the only 3-probe meter on the market) so you'll know the TDS of the 1) tap water, 2) RO water, and 3) DI water.

The two probe meters were really designed for use on an RO, not an RODI.
