K2 or Ride would be the cheaper options, If you think you’re really going to like it look at Burton, Neversummer or O-sin. Dont get sucked into buying and M3 or a Forum, its a waste on a beginner.
I’ve always love Burton bindings, they’re new ones are fantastic. But every person has a preference. I would say dont go buying bindings/board/boots without renting and trying different equipment. That way when you go the the shop you can say, “I like a tight feel in the boots but a looser binding” Just to have something to say about how you want the setup to feel, so the shop guy has somewhere to lead you.
My boardshop back home used to let you lease boots, which was great cause every year I got to try something new, and if the boots really sucked I could swap them out for somethign else.
