pH Tester?

I have been using API test kits, including the pH tester, but I struggle to decide if the color I am seeing is 7.8 or 8.2... Obviously, the difference is significant.

What digital meters would you folks recommend for my tired old eyes?

I don't have an RFL, I was kinda hoping for a handheld device of some kind. Anyone else have a favorite?
