Two Cherries is a well known, quality brand, I have bought their carving chisels in the past.

Lately I have been buying used from a tool guy at a local antique flea market. I buy old Sheffield chisels and gouges for 6-10 dollars each in great condition.

Look around, right now, there is a new never used, Boxed 6 piece, Two Cherry Firmer Chisel set on Craigs list, 120 bucks.
