Yes Wojtku, one of common beliefs at home is that luthier's built guitars cost a fortune...please, make the comparison with the world outside to see that it is not so bad... it is possible to find really nice instrument for ca 2000 Euro and if used - for much less.
The instrument presented at this Polish luthiers forum - sorry, I have no idea about the eventual price; I will pass your question to the builder/constructor of this guitar.
If you feel like being in touch with me I would suggest to begin email contacts: send me a private message if you would like my email address.
Soon I'll give you contact data to the constructor of this guitar.
