Hi The price of the spin isn’t just the cost of the masks. There’s a non-trivial cost involved in the redesign of the chip and the testing that finds the problem.
You can indeed do a project run for $5,000 and get usable chips. The same process moved to a single wafer also can give you a few thousand (maybe) of some very expensive dice. If you want a proper mask set and high volume / low cost tooling - it’s not cheap.
