Used butter/jib board models

I've been riding a fairly stuff all mountain board (atomic hatchet) for about 15 years. I find myself spending most of my time on narrow trails, side hits, and park features though and I'm looking for a board to really get the most out of this riding style.

I'm trying to keep the budget low (<$300 combined board and bindings) so I'm shopping used but there are so many older models to choose from that it's hard to sift through it all. Are there any specific models that really stand out from the last 10 years that are in this price range? I'm looking for super soft flex rocker boards, and 3D/spoon rocker on the tips if possible. I remember the skate banana from back in the day, those still seem to be floating around, any others?
