I used to be HUGE into longboarding, but got out of it just 2 years ago. I'll just say there's TONS of stuff out on the market now...it's absolutely insane how far the industry has come since 2009 when I stopped paying as much attention as I did. I'm sure someone more knowledgable than me can elaborate a little more, but I've always liked Earthwing's offering for beginner boards. I should note though, it's not as much like snowboarding as you'd think...again, there's gonna be some disagreement with me since I don't know the ropes of snowboarding 100%, but a LOT of people I've talked to comment on how different the two activities are. Finally, if you're interested in buying used, I've got a 38" longboard deck for sale; $75 shipped (USPS priority, with a confirmation number) for the deck alone, and you'd have to supply the trucks and wheels.
I kill the bunny hill!
