Anything less than 50 dollars valued and the skis become more of a decoration to hang on a wall rather than being ridden.
Real talk tho I like buying beat skis for cheap 50-150 with edge cracks and delam just cause I can stretch the life of the skis with my surgical-esque epoxying/repairing skills. Also great to have no edges underfoot cause then no rail is ever sticky again, and I HATE sticky rails.
