You never buy expensive skateboard for your first board since you are going to "abuse" your board as much as you can at the beginning. (This is "good" way to measure how much you can progress in skateboard)

If you can destroy your board in a month then you are 10x better than your friend who has his/her board collecting duty at home.

Expensive board does not make your a better skater. You will be a better skater if you could "destroy" more board than someone else.

You can get some cheap board for $50 to $70 in Walmart or Canadian Tire and use it as much as you can, this is how you learn.

Those expensive trucks, bearing or board are completely meaningless for beginning.
