I may just get a PinPoint. I have trouble discerning the color changes even
when being careful about using a white background and flourescent or
sunlight as a source.

Is there a titration style pH test kit available? All the ones I've seen
have you fill a vial with water to a line then put three drops of test
fluid
and have you match colors.

No, one doesn't exist. Remember, pH is the log10 of H+ concentration, so
there isn't a good linear correlation. At pH 6 there are 10 times the H+
of pH7, at pH 5 there are 100 times the H+ concentration at pH7, etc, etc.
If you need pH to better than +/- 0.2 get a PinPoint, I've seen them around
$85US.
