I am surprised these are not being snapped up. With Andrea_Mori Well Tempered Master Clock Driscol pcb and you have a clock that beats most everything available and digital music that rivals analogue.
On last year's pcb, the oven improves the sound, but it is still very good without the oven. The oven is a pain to build and dial in.
The new PCB does not need the oven but it only supports up to 25mHz.
