I just want something for my personal edification when sampling. I can't afford a YSI or anything remotely in that price range, but I want something easier and quicker to use than a reagent kit.
This is the closest I have found to what I want, but it only ranges up to 9990 μS (about 1/5 the salinity of seawater):

I've been using a Hanna Instruments TDS 1 meter that I bought 6 years ago for $15 as a special offer. I think they typically sell for $30-40. I've been happy with it, but it is a low-range meter as described above. YSI equipment is great but I'm not on a guvmint grant either.

I use a similar instrument in my lab here at work. Don't let that limited range stop you. If you have a sample outside the range, simply dilute it accordingly with distilled water and back calculate. Not a lot of work.
