I agree with Cole; there isn't a inexpensive meter worth anything...not even to give an indication or a base to work from. There are professional soil testing labs that will give all the information you need or want for not much money and their equipment costs a whole lot more than any of us could possibly afford. Besides that the technicians know how to prepare the samples properly to run the tests. Fifteen bucks every other year is worth it to me.
