Actually you most likely wouldn't be saving much money going Chinese. They ceased production years ago so supply is dry, I've noticed they sell for high amounts on the second hand market.
I wouldn't sell mine (CPS1) for less than $350 AU as it works great (onscreen menu, instant loading), gives me a handful of really expensive games that I can play on original hardware, and I would simply never be able to replace it due to them no longer being manufactured. The newer (Chinese) versions which are difficult to obtain sell for considerably more than that anyhow. End of the day it's still an original A and C board which sell for enough as is, let alone being combined with a custom B board.
