TDS meter/tester Q's

[glxtrix]

So I'm looking into getting one of these and I've seen all kinds of prices rangin from 10 bux up to whatever you want to spend....My question, is a TDS meter/tester the same as any? Or are there really big differances?
Here are some examples:

Your 10 dollar one - http://www.jr.com/JRProductPage.process?Product_Id=4137972&JRSource=googlebase.datafeed.LLT+WPT1000">http://www.jr.com/JRProductPage.process?Product_Id=4137972&JRSource=googlebase.datafeed.LLT+WPT1000</a>

Here is a hanna for 15. I've heard this name befor associated with these testers, anyone reccomend these over others?

Then the filter guys sell some as well -

I have the simplier Hanna TDS1 model that is similiar to the one that BigD placed a link about. Mine will measure 0-999 ppm and automatically temperature calibrates.

It's a fine TDS meter that's been in use for 6+ years and is still very reliable.

Hope this helps you decide.
