I have an ADVC 300 for sale that is like new. Includes original manual and CD along with component and AV cable and power supply. If I can locate the 6pin to 4pin firewire cable I will also include it. I never used this unit much at all and it's in excellent shape.
I'm asking $325 for it including shipping (U.S. only, sorry) I accept Venmo or money order. Shipping would be USPS Priority Mail or FedEx.
