I considered digital, but decided against it: You're looking at $100-500 per analyzer + calibration solutions + replacement probes occasionally + an expected service life of 5-10 years (??). You get what you pay for and if you go with the cheap-o meter, it may say everything is fine when you actually have major problems. . .
For a fraction of the price you can get wet chemistry test kits. A little more of a hassle, but very reliable and plenty accurate.
