Look at it this way; sooner or later you're definitely going to want a new board but considering the fact that you're just starting to park your board is going to get a good slapping.
It's either you spend money on an old board for you to scratch/rape/ burn/ probably break if you go hard/or if it's in bad condition.
You can get a new board, might end up lasting you longer than the board that you're about to buy, feel the chills of having a new board & set up.
It's near the end of the riding season so everything will be on sale so it's the perfect time to buy if you decide to.
Question is are you willing to spend the money?
If you'd like to spend minimally I suggest just buy your own set up that way you don't have to buy a used board and later buy a new board. But if you're financially capable go for it.
