Looking to get some gear this year and I need advice

I’ve been snowboarding for a few years but haven’t gone a ton throughout then. I’ve always just rented the package deal of boots, a board, and a helmet from the resort but this year I wanna really get into it because I had a blast last winter!

I’m definitely buying a season lift pass but I’m not sure which gear I should buy new, which used, and if I should keep renting any of it. I’m definitely going to be buying boots and a helmet new, any advice where to get those? I’m also not sure on bindings and a board, should I check eBay for both? Just go for a new board? And where should I look? I don’t have a ton of money to spend but I’m willing to put in a decent amount cause I know this won’t be cheap

If it helps, I’m looking for an all-mountain style board, preferably twin (doesn’t have to be perfect) I’ve gotten comfortable riding blues and am gonna move up to blacks and definitely some park this winter
