Joe,
Not many top steel-string builders fit the bill as top classical builders. John Mello might be one, and I know Matt Mustapick builds in a classical vein.
I recommend a fellow here in Eugene,
Anders Sterner.
Anders and I have talked quite a bit about nylon string guitars as they might be used for someone like myself...nothing directly in the works yet (for me), but Anders understands and respects fingerstyle music.
