This is an unused , built-to-order unit, from Q5 Signal LLC, that I've had for about a year. I never put it into service in the shack and have since decided to go a different route for 23cm. The transverter has the following specs: common IF (144 MHz) , 1 to 10 watt drive level, PTT (low), optional internal high stability LO, built-in sequencer , cooling fan. The unit comes with documentation and a power cable ( 13.8 VDC at 10 amps max). The transverter was bench tested and is working fine. Sorry I can't find the original box (nothing too cool anyway - plain white). My cost was over $650 (plus a 6-week wait time ;-). Shipping is a flat $35 to the lower 48. I'll refund any overage.
