My family has always loved Bisquick pancakes. My mom made them thin, but my DH liked them thick - just vary the amount of milk you add to make the batter thinner or thicker. I sometimes add a little extra sugar (maybe a teaspoon) to the batch. You might ask your husband if he prefers his pancakes thin or thick, which will probably matter more to him than the brand of mix. Bisquick, Hungry Jack, and Aunt Jemima (which I think has recently been relabeled as Pearl Milling) are probably the most commonly used mixes.
As an added bonus to Bisquick, there are countless types of recipes to use it in. There will be some of the most popular recipes printed on the box, but many more are available online or in cookbooks. In the summer, Bisquick shortcake for strawberry shortcake is another favorite.
Here’s a video of three chefs comparing pancake mixes. They didn’t agree on which was best, although none chose Bisquick.
By all means, get kitchen scales if that’s what your recipes call for, but American recipes tend to measure with the less accurate cup/spoon method, so you might also want to pick up a set of measuring cups and spoons.
