Has anyone tried the Hanna Instruments pH meters? What do you think of them? Are they worth anything?
I need to get a pH meter for cheese making. I don't want to spend a million dollars on one but would like a meter that is both precise and accurate. I have seen mixed reviews on Hanna pH meters.
Which model? Their higher end ones are alright.
ha ha, yeah, I forgot to post the links:

I am also considering (based on other comments I have read):

I am willing to spend over $100 for a reliable pH meter, but not too much more unless the marginal benefits really outweigh the marginal costs (I am not looking for a meter that is accurate to 0.000001, I don't need the ability to detect a single hydronium ion), but I would like a precision of at least 0.01. I definitely want to spend less than $200, and strongly want to spend less than $130. Temperature compensation would also be nice. (and it would be nice if the replacement parts do not cost more than the meter itself.... I don't buy lexmark printers for a reason ;))
If anyone has other suggestions besides the ones listed above, I am all ears
