It can depend on where you’re located and how deep you get into the sport. For beginner classes, in my area, they are ~$100 for 6 weeks. It gets more expensive once you need your own gear and if you choose to compete and/or take private lessons.
I think the most comparable comparison in costs are probably club hockey and club soccer.
I haven’t made any this year, but I have in the past. My favorite flavor I’ve made is a chai ice cream (just brew the tea in the ice cream base).
