Under $100: Not really a purchase, but a habit that involved several purchases. Making L. Reuteri "Yogurt" using half & half, biogaia tablets, mason jars, and a sous vide. Helped with gut issues.

Under $1000: An Ooni pizza oven. It's a relatively low-stakes investment and you can produce some pretty phenomenal pizzas after you get over your first few "catastrophe calzones". Just a nice weekend dad hobby.
