In general, you should pay more for extra chips if you have an edge. Eventually, the declining marginal value to chips would dominate. It might be that the first 1000 chips are worth $135 to a good player and the next 1000 chips are worth $115; $100 and $90 to an average player; and $60 and $50 to a bad player. These are guesses.

In a multitable tournament, I think the value is much closer to linear at the start.
