Trying to find a good EC, TDS monitor

Hello,
I want to buy a TDS/EC monitor but I am not sure what to chose (too many option). I like the monitors from American Marine but it looks like they don't do this one ;(.
However, I found an other one from Milwaukee: Here it is
Does someone know about this monitor? Would it be a good choice?

I already have a pH monitor so I don't really need that feature on my new monitor. If you know an other model that does not have pH on it, please let me know.

Thanks lot.

 

I just bought one from marineandreef.com (Sorry don't know how to make link) but just search TDS. I haven't received it yet so cannot comment on the performance or anything but it seemed like a good deal

 

These are the best ones I've seen (or ones of similar design). They work inline so you just have to press the on button once in a while to check how your membrane is performing and how your DI is performing (put one before and after your DI stage). Pretty cheap too.
Dual inline TDS meter DM-1 HM Digital - English

 

Hanna makes what you need.
