So did you ride enough to know you will like it? A new rider to the game is always awesome, but there is no point in buying gear if you aren't sure your going to be completely into it.
I rented a few times before I bought my first board.
I'm pretty sure I liked it, I sucked a lot when I used to go but I enjoyed it. The only thing that stopped me was the lack of people to do it with and driving for 2 hours by myself to spend a weekend by myself wasn't something I wanted to do then. Now I simply don't care and just want to snowboard.
On that note, I might still end up hitting the slopes this season using rental before actually purchasing.
