Newbie and learning - need a board

Just started learning to Snowboard on a dry ski slope with a holiday booked for the beginning of February to Andorra.
What I am after is a board. I am quite heavy 90kg`s and will generally use the board on a dry slope the majority of the year with the odd occassion on the real thing.
What type of board is best?

You`re going to the right place to buy - tax free and all - but like you say, you`ve just started out. Calm down baby. Snow and plastic don`t mix well unless all you intend doing is jibbing on snow. Plastic feck`s up yr board big time. This is just my opinion, and I`m sure the big boys will tell me I`m wrong, buy a board that you like on snow, use hire`s for plastic. When the time comes, down grade yr 2003 board to a dry life and buy a newbie for snow.
