Go
here and have some lessons, they will provide kit, usually in with the cost (except a jacket/trousers/gloves/hat)
Have a few lessons so you can toe/heel edge, turn, stop, get up when you fall over, get on a drag lift
Then go to a resort for a long weekend and rent kit for a couple days to see if you can hack powder, cus its tottally different to dry!
Then, if you really like it and you have the cash to go to a resort at least once a year buy your own kit!
