I have 2 different Carvewrights for sale. One is a model A Compucarve and the other a newer B Carvewright. Both have dust collection for them and rock chucks installed for easy bit installation. The A comes with the large designer bit set and the B comes with the scanner probe (never used). Email me at cpuman6mgl@gmail.com or call me at 901 413 3005. $1000.00 each. Johnny
