I'm about 180 and I am riding a 156 2010 Sierra Crew.
I love the board. I have never ridden a Custom so I can't compare it but I was very happy with the board at $250 (with a free pair of goggles).
I don't park or pipe, just some flat land jumps now and again.
The top sheet is fragile. And slippery. Are you getting a five year board for $99? Probably not. Wear and tear has been worse in one season than I have seen on any board I have had previously. Base seems fast enough, fast enough for me at any rate and, as I said, I am very happy with it.
For $99 bucks, if the 156 fits you, and if you have been riding for at least a season (the board is a bit stiff at first, I think it might also be too fast for a true beginner) I would not hesitate.
