I have four Conant Ball dining room table and side chairs that I've
become very attached to. Problem is that the chairs (mid-century
modern) are showing their wear and should probably be replaced or
perhaps refinished. Can't find any furniture showroom which is still
showing these particular chairs except on ebay for $150 each plus $50
ship.

What does it generally cost to restore/refinish chairs or would it make
more sense to bite the bullet and replace them?

Any friendly suggestions?
