This is brilliant! Let me know if you need more testing, I could do it and I live next to the french border in Roses (Girona).

you can found my own solution there:
http://www.nicekits.fr/perso/SYNCH-CORRECTOR-FOR-IKEGAMI-1990R.zip

you'll find source files with programs, schematic and pcb for eagle cad soft, a pinout and functionnal diagram and two example of use with BNC or SCART.

my solution works for me but all of components are used at there maximum of speed.
and sometime, on white screen one PCE you can have jumps of screen on the PCE, but that depend of the extron or the reactivity of NAND includes inside.
YOU MUST use really really fast NAND. and YOU MUST use X2 capacitor for the LM1881.

if someone want to test, i have 8 blank PCB in stock

i cand sen you the critical component (PCB + super fast nands + X2 Capacitors) for 8€+shipping cost.
you will add ~40/50$ of components, that depends where you come from.

but for the moment i have not enough time to produce more fully assembled converters.
