Yeah, I am afraid that Beyond and the FB3/4 DACs have lowered the value of the QMs. Realistically, it makes sense. Out with the old and in with the new. USB and Network interface make the new DAC solutions a much more viable option. I try to keep looking toward the future. I paid $500 over the years for various HeNe's, $2000 for an air cooled ALC60x, $1200 for my QM (intro), $800 for my 100mW 473nm DPSS and $400 for my 50mW 532 DPSS... I can't look back, I just need to keep looking forward.
