I was not thrilled with the Hanna pH/conductivity pen I've been using — takes forever to come to a stable reading, so I splurged on a Bluelab soil pH pen. Not only can you use it to measure pH of liquids, you can put it directly into the soil and get good, stable readings. Anyway, after using it, I'm now thrilled. It got just about the same pH putting the probe directly in the soil as the slurry pH. I have a feeling I might go off on a soil pH reading-spree.
